Yves, Felix,

I guess that indeed the wording I proposed was ambiguous. Thus, I will
have to work on a modification ... Stay tuned.

Best regards,
Christian

I think so too. Maybe the wording is a little bit ambigous? Christian,
Sebastian, do you agree with Yves interpretation?

At
http://www.w3.org/International/its/itstagset/itstagset.html#def-selecto
r
, we have

[[Selection relies on the information which is given in the XML
Information Set [XML Infoset]. ITS applications may implement inclusion
mechanisms such as XInclude or DITA's [Dita 1.0] conref.]]

which I wrote during the f2f, having Yves interpretation in mind.

Both XSLT and XQuery operate on a datamodel which is an extension of the
 XML Infoset. These specs define what is in this data model, but not how
it is constructed, see
http://www.w3.org/TR/xquery/#id-data-model-generation :
[[An XDM instance might also be synthesized directly from a relational
database, or constructed in some other way (see DM3 in Fig. 1.) XQuery
is defined in terms of the data model, but it does not place any
constraints on how XDM instances are constructed.]]

So these specs do not say nothing, but say "you can do everything to
create a data model instance, but it is your responsibility, and we
don't care."

I don't know how to word that, though ...
