The XML Core Working Group invites implementation of the Candidate Recommendation of XML Inclusions (XInclude) Version 1.1. Many programming languages provide an inclusion mechanism to facilitate modularity. Markup languages also often have need of such a mechanism. This specification introduces a generic mechanism for merging XML documents (as represented by their information sets) for use by applications that need such a facility. The syntax leverages existing XML constructs – elements, attributes, and URI references. Learn more about the Extensible Markup Language (XML) Activity.
