href

XInclude Href Linking Mechanism

A URI reference (or an IRI reference) that specifies the location of the resource to include. (See W3C XInclude documentation (http://www.w3.org/TR/xinclude/.)

Remarks

This attribute is only used for the <xi:include> element; most elements in this Tag Set use the XLink href attribute (@xlink:href).
According to the W3C documentation:
The href attribute is optional; the absence of this attribute is the same as specifying href='', that is, the reference is to the same document. If the href attribute is absent when parse="xml", the @xpointer attribute must be present. Fragment identifiers must not be used; their appearance is a fatal error.

Used on Element: <xi:include>

ValueMeaning
Text, numbers, or special charactersThe URI of a resource to be included.
Restriction@href is an optional attribute; there is no default.
