The XML Core WG does not see a practical problem here, given that the
processing model of casting to XML, XML parsing, XPointer parsing, and
XPointer resolution provide three barriers to bad effects arising from
inconsistencies in the media types.  To rework this would represent a
large functionality loss and intrusive changes not warranted by
implementation feedback.

In addition, since this issue has been forwarded to the TAG, we feel the
issue can still be addressed in the Director's decision to move XInclude
to PR, if you disagree with our resolution.

We accept this comment and plan to wait until XPointer becomes a
Recommendation before advancing XInclude to PR.

The XML Core WG does not feel holding up XInclude for this purpose is
warranted, as there are no candidates for XPointer fragment syntax at
this time other than the XPointer features we have identified in the
