Michael Glavassevich commented on XERCESJ-1113:
-----------------------------------------------
Requirements for the XNI component. It needs to:
1) Normalize the value of each xml:id attribute.
2) Perform ID type assignment with the normalized value (in other words give it
an ID type if it doesn't already have one).
3) Report an error if the constraints on the xml:id are violated (in other
words validate the xml:id).
4) Pass the processed xml:id attribute (and other XNI events) to the next
component in the pipeline.
> [GSoC]: Support for xml:id
> --------------------------

> Key: XERCESJ-1113
> URL: https://issues.apache.org/jira/browse/XERCESJ-1113
> Project: Xerces2-J
> Issue Type: New Feature
> Components: XInclude 1.0
> Affects Versions: 2.7.1
> Environment: All
> Reporter: George Cristian Bina
> Labels: gsoc2011

> Hi,
> The XInclude ID support should handle xml:id. This is useful for instance
> with DocBook or TEI that use Relax NG schemas for validation and also need
> XInclude support.
> Here it is a patch that adds support for handling xml:id attributes as
> attributes of ID type.
