Definition: The BASE element allows a document's URL to be recorded in situations in which the document can be read out of context. The URLs that are found within a document may be in a "partial" form that is relative to this base address. The URL used to retrieve the document is the default base address.
Standard Attribute: ID
Implies that the anchor serves as the beginning of a hypertext link. The link's destination is designated by the HREF attribute's value as expressed in the notation of the URI (Universal Resource Identifier).
ID is an SGML identifier. You can use it as the target for hypertext links or to name specific elements in associated style sheets. Because identifiers are NAME tokens, they have to be unique within the scope of the current document, an attribute which overrules the NAME attribute described below.
