If the HREF attribute is present, the anchor is sensitive text: the start of a link. If the reader selects this text, (s)he should be presented with another document whose network address is defined by the value of the HREF attribute.
CDATA
The METHODS attributes of anchors and links provide information about the functions which the user may perform on an object. These are more accurately given by the HTTP protocol when it is used, but it may, for similar reasons as for the TITLE attribute, be useful to include the information in advance in the link. For example, the browser may chose a different rendering as a function of the methods allowed (for example something which is searchable may get a different icon).
The value of the METHODS attribute is a comma separated list of HTTP methods supported by the object for public use.
NAMES
If present, the attribute NAME allows the anchor to be the destination of a link. The value of the attribute is an identifier for the anchor. Identifiers are arbitrary strings but must be unique within the HTML document. Another document can then make a reference explicitly to this anchor by putting the identifier after the address, separated by a hash sign.
CDATA
An attribute REL may give the relationship (s) described by the hypertext link. The value is a comma-separated list of relationship values. Values and their semantics will be registered by the HTML registration authority . The default relationship if none other is given is void. REL should not be present unless HREF is present.
NAME
The same as REL , but the semantics of the link type are in the reverse direction. A link from A to B with REL="X" expresses the same relationship as a link from B to A with REV="X". An anchor may have both REL and REV attributes.
NAME
Attribute for easy transformation to the International Committee for Accessible Document Design (ICADD) DTD. ICADD applications are designed to support usable access to structured information by print-impaired individuals through Braille, large print and voice synthesis.
CDATA
This is informational only. If present the value of this field should equal the value of the TITLE of the document whose address is given by the HREF attribute.
CDATA
If present, this specifies a uniform resource number for the document.
