Common Attributes 

type +'a attrib
val to_xmlattribs : 'a attrib list -> Xml.attrib list
val to_attrib : Xml.attrib -> 'a attrib

'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.

val a_wrap : [< `Hard | `Soft ] -> [> `Wrap ] attrib
val a_class : Html5_types.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_user_data : 
  Html5_types.nmtoken ->
  Html5_types.text -> [> `User_data ] attrib

May be used to specify custom attribs. The example given by the W3C is as follows : {{{<ol> <li data-length="2m11s">Beyond The Sea</li> </ol>}}} It should be used for preprocessing ends only.

val a_id : Html5_types.text -> [> `Id ] attrib

This attribute assigns a name to an element. This name must be unique in a document. The text should be without any space.

val a_title : Html5_types.text -> [> `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.

This attribute assigns an access key to an element. An access key is a single character from the document character set. NB: authors should consider the input method of the expected reader when specifying an accesskey.

val a_charset : Html5_types.charset -> [> `Charset ] attrib

This attribute specifies the character encoding of the resource designated by the link. Please consult the section on character encodings for more details.

val a_accept_charset : Html5_types.charsets -> [> `Accept_charset ] attrib
val a_accept : Html5_types.contenttypes -> [> `Accept ] attrib
val a_href : Xml.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 : Html5_types.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 : Html5_types.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.

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 : Html5_types.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_mime_type : Html5_types.contenttype -> [> `Mime_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.

val a_datetime : Html5_types.cdata -> [> `Datetime ] attrib
val a_action : Xml.uri -> [> `Action ] attrib

This attribute specifies a form processing agent. User agent behavior for a value other than an HTTP URI is undefined.

val a_checked : [< `Checked ] -> [> `Checked ] attrib

When the type attribute has the value "radio" or "checkbox", this boolean attribute specifies that the button is on. User agents must ignore this attribute for other control types.

val a_cols : Html5_types.number -> [> `Cols ] attrib

This attribute specifies the visible width in average character widths. Users should be able to enter longer lines than this, so user agents should provide some means to scroll through the contents of the control when the contents extend beyond the visible area. User agents may wrap visible text lines to keep long lines visible without the need for scrolling.

val a_enctype : Html5_types.contenttype -> [> `Enctype ] attrib
val a_for : Html5_types.idref -> [> `For ] attrib
val a_for_list : Html5_types.idrefs -> [> `For_List ] attrib

val a_multiple : [< `Multiple ] -> [> `Multiple ] attrib
val a_name : Html5_types.text -> [> `Name ] attrib

This attribute assigns the control name.

val a_rows : Html5_types.number -> [> `Rows ] attrib

This attribute specifies the number of visible text lines. Users should be able to enter more lines than this, so user agents should provide some means to scroll through the contents of the control when the contents extend beyond the visible area.

val a_selected : [< `Selected ] -> [> `Selected ] attrib

When set, this boolean attribute specifies that this option is pre-selected.

val a_size : Html5_types.number -> [> `Size ] attrib
