THE XML REVOLUTION - TECHNOLOGIES FOR THE FUTURE WEB

XInclude details

How is the included resource denoted?

with XPointer (described later...) - an extension of URLs that can address document nodes, node sets, or character data ranges

Other issues:

with parse="text" and encoding="..." attributes, a resource can be transformed into a character data node before inclusion
XInclude processors may need to create namespace declaration attributes to ensure equivalence

Many XInclude processors support only whole-document URIs, not full XPointer.
