XML Base

XML Base allows developers to specify a document’s base URI. Other links within the same document can then specify links relative to this base. These links could then point to applets, style sheets, images and other files. The syntax for XML Base consists of a single XML attribute named xml:base.

A simple example follows for xml:base in a document with Xlink follows.
