If someone argues that supporting schema complex types, bloats the spec, complicates the use of the language, and provides lots of undesirable side effects. Being told that you can use Xpath/XSLT without using that feature is I suppose better than nothing, but hardly a justification for the schema complex type support being there in the first place. > I can't see anything in the XSLT 2.0 WD that says that, during > compilation, it will access a particular instance document's schema > and use that to optimise queries. Neither could I actually, but this so far has been the only justification offered for the provision of strong typing based on schema complex types, so if it is Xquery only, what's it doing in Xpath? > If a processor substituted aaa/bbb for the empty sequence on > the assumption that the source document was completely valid, there > would be a rather strange situation where the data model contained an > element that was inaccessible from the stylesheet. You say it's strange, and I agree, but neither of us are on the WG, It's hard to understand how the argument that the type system allows compile time optimisation (if it is true) can fail to lead to this strange situation.
