Missing set-xml-id in xi:include?

[Thomas Schraitle <tom_schr@web.de>]

Hi,

just read Jirka's "DocBook Transclusion"[1] document. In Appendix A. "Using
XInclude 1.1 features for your content" there is Example A.3 "Using set-xml-id
to remove the top-level ID during transclusion".

The set-xml-id attribute is mentioned in the XInclude 1.1 specification[2].

However, when you search for set-xml-id in DocBook 5.2CR3 it's missing. This
attribute isn't available in docbookxi.rn{c,g} at all. Is this an omission?

With the current implementation, the above mentioned example wouldn't be
possible and would raise a validation error. :)
