yes that's what I meant.

well yes and no.
If you (and I) want to have some kind of mini schema type assignment
within xslt then that means some kind of minimal support for
prim^H^H^Hbuilt in types. However you could support defaulted attributes 
and even maybe user defined complex types to a certain amount just by
taking a PSVI as input, from your mythical PSVI enhanced SAX stream.
If the PSVI says that some element has a value defaulted by the schema
and has type xx:yy then it is maybe possible to imagine accessing both
the defaulted value and the type in XPath just essentially as a label
without it having to know anything deep about how types are structured,
inherit etc.

yes it was the latter I last used and probably had in mind:-)
