Module XHTML.M

module M: T

The elements, attributes, attribute types and data types are given names that match the names in the W3C recommendation as closely as allowed by a strict typing discipline and the lexical conventions of O'Caml:

elements are implemented as O'Caml constructors with the same name as in the W3C recommendation. The domain and codomain are specified as 'a elt, where 'a is a concrete phantom type build out of polymorphic variants.
attributes are implemented as O'Caml constructors with a_ prefixed to the name. The name is the same as in the W3C recommendation, unless an additional prefix is required to disambiguate:
- a_fs_rows and a_fs_cols instead of a_rows and a_cols for framesets, because of the different argument types.

attribute types are implemented as O'Caml types that all have the same names as in the W3C recommendation, but are all lowercase.
data types are also implemented as O'Caml types that all have the same names as in the W3C recommendation and are again all lowercase.

Finite sets of alternatives are mapped to polymorphic variants.

The phantom type is always the most general required by any (supported) version of the standard. Type discipline is enforced by exporting or not-exporting the corresponding constructor.

Attribute Types ¶

type cdata = string

Character data

type id = string

A document-unique identifier

type idref = string

A reference to a document-unique identifier

type idrefs = idref list

A space-separated list of references to document-unique identifiers

type name = string

A name with the same character constraints as ID above

type nmtoken = string

A name composed of only name tokens as defined in XML 1.0
See also XML 1.0

type nmtokens = nmtoken list

One or more white space separated NMTOKEN values

type pcdata = string

Processed character data

Data Types ¶

type character = char

A single character from ISO 10646.

type charset = string

A character encoding, as per RFC2045 (MIME).
See also RFC2045

type charsets = charset list

A space-separated list of character encodings, as per RFC2045 (MIME).
See also RFC2045

type contenttype = string

A media type, as per RFC2045 (MIME).
See also RFC2045

type contenttypes = contenttype list

A comma-separated list of media types, as per RFC2045 (MIME).
See also RFC2045

type coords = string list

Comma- separated list of coordinates to use in defining areas.

type datetime = string

Date and time information.

type fpi = string

A character string representing an SGML Formal Public Identifier.

type frametarget = string

Frame name used as destination for results of certain actions.

type languagecode = string

A language code, as per RFC3066.
See also RFC3066

type length = [ `Percent of int | `Pixels of int ]

The value may be either in pixels or a percentage of the available horizontal or vertical space. Thus, the value `Percent 50 means half of the available space.

Authors may use the following recognized link types, listed here with their conventional interpretations. A LinkTypes value refers to a space-separated list of link types. White space characters are not permitted within link types. These link types are case-insensitive, i.e., "Alternate" has the same meaning as "alternate".

User agents, search engines, etc. may interpret these link types in a variety of ways. For example, user agents may provide access to linked documents through a navigation bar.

`Alternate: Designates substitute versions for the document in which the link occurs. When used together with the hreflang attribute, it implies a translated version of the document. When used together with the media attribute, it implies a version designed for a different medium (or media).
`Stylesheet: Refers to an external style sheet. See the Style Module for details. This is used together with the link type "Alternate" for user-selectable alternate style sheets.
`Start: Refers to the first document in a collection of documents. This link type tells search engines which document is considered by the author to be the starting point of the collection.
`Next: Refers to the next document in a linear sequence of documents. User agents may choose to pre-load the "next" document, to reduce the perceived load time.
`Prev: Refers to the previous document in an ordered series of documents. Some user agents also support the synonym "Previous".
`Contents: Refers to a document serving as a table of contents. Some user agents also support the synonym ToC (from "Table of Contents").
`Index: Refers to a document providing an index for the current document.
`Glossary: Refers to a document providing a glossary of terms that pertain to the current document.
`Copyright: Refers to a copyright statement for the current document.
`Chapter: Refers to a document serving as a chapter in a collection of documents.
`Section: Refers to a document serving as a section in a collection of documents.
`Subsection: Refers to a document serving as a subsection in a collection of documents.
`Appendix: Refers to a document serving as an appendix in a collection of documents.
`Help: Refers to a document offering help (more information, links to other sources information, etc.)
`Bookmark: Refers to a bookmark. A bookmark is a link to a key entry point within an extended document. The title attribute may be used, for example, to label the bookmark. Note that several bookmarks may be defined in each document.
`Other: refers to any other type (for example icon or shortcut).

The MediaDesc attribute is a comma-separated list of media descriptors. The following is a list of recognized media descriptors:

`Screen: Intended for non-paged computer screens.
`TTY: Intended for media using a fixed-pitch character grid, such as teletypes, terminals, or portable devices with limited display capabilities.
`TV: Intended for television-type devices (low resolution, color, limited scrollability).
`Projection: Intended for projectors.
`Handheld: Intended for handheld devices (small screen, monochrome, bitmapped graphics, limited bandwidth).
`Print: Intended for paged, opaque material and for documents viewed on screen in print preview mode.
`Braille: Intended for braille tactile feedback devices.
`Aural: Intended for speech synthesizers.
`All: Suitable for all devices.

Future versions of XHTML may introduce new values and may allow parameterized values. To facilitate the introduction of these extensions, conforming user agents must be able to parse the media attribute value as follows:

The value is a comma-separated list of entries. For example, is mapped to: "screen", "3d-glasses", "print and resolution > 90dpi".
Each entry is truncated just before the first character that isn't a US ASCII letter [a-zA-Z] (ISO 10646 hex 41-5a, 61-7a), digit [0-9] (hex 30-39), or hyphen-minus (hex 2d). In the example, this gives: "screen", "3d-glasses", "print".
A case-insensitive match is then made with the set of media types defined above. User agents may ignore entries that don't match. In the example we are left with "screen" and "print".

Note. Style sheets may include media-dependent variations within them (e.g., the CSS @media construct). In such cases it may be appropriate to use "media=all".

type multilength = [ `Percent of int | `Pixels of int | `Relative of int ]

The value may be a Length or a relative length. A relative length has the form "i*", where "i" is an integer. When allotting space among elements competing for that space, user agents allot pixel and percentage lengths first, then divide up remaining available space among relative lengths. Each relative length receives a portion of the available space that is proportional to the integer preceding the "*". The value "*" is equivalent to "1*". Thus, if 60 pixels of space are available after the user agent allots pixel and percentage space, and the competing relative lengths are "1*", "2*", and "3*", the "1*" will be allotted 10 pixels, the "2*" will be allotted 20 pixels, and the "3*" will be allotted 30 pixels.

type multilengths = multilength list

A comma separated list of items of type MultiLength.

type number = int

One or more digits.

type pixels = int

The value is an integer that represents the number of pixels of the canvas (screen, paper). Thus, the value "50" means fifty pixels. For normative information about the definition of a pixel, please consult CSS2.

type script = string

Script data can be the content of the "script" element and the value of intrinsic event attributes. User agents must not evaluate script data as HTML markup but instead must pass it on as data to a script engine.

The case-sensitivity of script data depends on the scripting language.

Please note that script data that is element content may not contain character references, but script data that is the value of an attribute may contain them.

type text = string

Arbitrary textual data, likely meant to be human-readable.

type uri

val uri_of_string : string -> uri

val string_of_uri : uri -> string

A Uniform Resource Identifier, as per RFC2396.
See also RFC2396

type uris = uri

A space-separated list of Uniform Resource Identifiers, as per RFC2396.
See also RFC2396

Common Attributes ¶

type +'a attrib

type +'a attribs

val to_xmlattribs : 'a attrib list -> XML.attrib list

'a is known as a phantom type. The implementation is actually monomorphic (the different element types are distinguished by a homogeneous variable, such as their textual representation) and the type variable `a is just used by the type checker.

NB: It might be possible to use polymorphic variants directly, without phantom types, but the implementation is likely to be more involved.

Core ¶

type core = [ `Class | `Id | `Title ]

val a_class : nmtokens -> [> `Class ] attrib

This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names.

val a_id : id -> [> `Id ] attrib

This attribute assigns a name to an element. This name must be unique in a document.

val a_title : cdata -> [> `Title ] attrib

This attribute offers advisory information about the element for which it is set.

Values of the title attribute may be rendered by user agents in a variety of ways. For instance, visual browsers frequently display the title as a tool tip (a short message that appears when the pointing device pauses over an object). Audio user agents may speak the title information in a similar context.

The title attribute has an additional role when used with the link element to designate an external style sheet. Please consult the section on links and style sheets for details.

I18N ¶

type i18n = [ `XML_lang ]

val a_xml_lang : nmtoken -> [> `XML_lang ] attrib

Style ¶

The Style collection is deprecated, because the Style Attribute Module is deprecated.

Events ¶

val a_href : uri -> [> `Href ] attrib

This attribute specifies the location of a Web resource, thus defining a link between the current element (the source anchor) and the destination anchor defined by this attribute.

val a_hreflang : languagecode -> [> `Hreflang ] attrib

This attribute specifies the base language of the resource designated by href and may only be used when href is specified.

val a_rel : linktypes -> [> `Rel ] attrib

This attribute describes the relationship from the current document to the anchor specified by the href attribute. The value of this attribute is a space-separated list of link types.

val a_rev : linktypes -> [> `Rev ] attrib

This attribute is used to describe a reverse link from the anchor specified by the href attribute to the current document. The value of this attribute is a space-separated list of link types.

val a_tabindex : number -> [> `Tabindex ] attrib

This attribute specifies the position of the current element in the tabbing order for the current document. This value must be a number between 0 and 32767. User agents should ignore leading zeros.

val a_type : contenttype -> [> `Type ] attrib

This attribute gives an advisory hint as to the content type of the content available at the link target address. It allows user agents to opt to use a fallback mechanism rather than fetch the content if they are advised that they will get content in a content type they do not support.Authors who use this attribute take responsibility to manage the risk that it may become inconsistent with the content available at the link target address.

Element Constructor Types ¶

type ('a, 'b) nullary = ?a:'a attrib list -> unit -> 'b elt

type ('a, 'b, 'c) unary = ?a:'a attrib list -> 'b elt -> 'c elt

type ('a, 'b, 'c, 'd) binary =
?a:'a attrib list ->
'b elt -> 'c elt -> 'd elt

type ('a, 'b, 'c, 'd, 'e, 'f) quadry =
   ?a:'a attrib list ->
    'b elt ->
    'c elt -> 'd elt -> 'e elt -> 'f elt

type ('a, 'b, 'c) star = ?a:'a attrib list -> 'b elt list -> 'c elt

Star '*' denotes any number of children, uncluding zero.

type ('a, 'b, 'c) plus =
?a:'a attrib list ->
'b elt -> 'b elt list -> 'c elt

Plus '+' requires at least one child.

Output ¶

?encode maps strings to HTML and must encode the unsafe characters '<', '>', '"', '&' and the control characters 0-8, 11-12, 14-31, 127 to HTML entities. XML.encode_unsafe is the default for ?encode in output and pretty_print below. Other implementations are provided by the module Netencoding in the OcamlNet library, e.g.: let encode = Netencoding.Html.encode ~in_enc:`Enc_iso88591 ~out_enc:`Enc_usascii (), Where national characters are replaced by HTML entities. The user is of course free to write her own implementation.

~encoding is the official name of the external character set encoding that is used by outs : string -> unit.

Tools ¶

val version : string

val standard : uri

val validator : uri

val validator_icon : unit -> [> `A ] elt

A hyperlink to the W3C validator, including the logo.
See also Validator

val addto_class : string -> 'a elt -> 'a elt

Add the element and all its subelements to a class. Note that this is only almost typesafe, because a few elements from the structure class do not support the class attribute. On the other hand, listing all allowed elements would be too tedious right now.

val addto_class1 : string -> 'a elt -> 'a elt

Add the element to a class.

val set_rowspan : int -> ([< `Td | `Th ] as 'a) elt -> 'a elt

Set the rowspan attribute for the element.

val rewrite_hrefs : (string -> string) -> 'a elt -> 'a elt

val tot : XML.elt -> 'a elt

val totl : XML.elt list -> 'a elt list

val toelt : 'a elt -> XML.elt

val toeltl : 'a elt list -> XML.elt list
