5.7.3. Anchor: A

The <A> element indicates a hyperlink anchor (see 7, "Hyperlinks"). At least one of the NAME and HREF attributes should be present. Attributes of the <A> element:

HREF

gives the URI of the head anchor of a hyperlink.

NAME

gives the name of the anchor, and makes it available as a head of a hyperlink.

TITLE

suggests a title for the destination resource -- advisory only. The TITLE attribute may be used:

• for display prior to accessing the destination resource, for example, as a margin note or on a small box while the mouse is over the anchor, or while the document is being loaded;

• for resources that do not include a title, such as graphics, plain text and Gopher menus, for use as a window title.

REL

The REL attribute gives the relationship(s) described by the hyperlink. The value is a whitespace separated list of relationship names. The semantics of link relationships are not specified in this document.

REV

same as the REL attribute, but the semantics of the relationship 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.

URN

specifies a preferred, more persistent identifier for the head anchor of the hyperlink. The syntax and semantics of the URN attribute are not yet specified.

METHODS

specifies methods to be used in accessing the destination, as a whitespace-separated list of names. The set of applicable names is a function of the scheme of the URI in the HREF attribute. For similar reasons as for the TITLE attribute, it may be useful to include the information in advance in the link. For example, the HTML user agent may chose a different rendering as a function of the methods allowed; for example, something that is searchable may get a different icon.
