On the first point: WSDL part 1 allows use of other schema languages.
" WSDL recognizes the need for rich type systems for describing message formats,
and supports the XML Schemas specification (XSD) as its canonical type system.
However, since it is unreasonable to expect a single type system grammar to be used
to describe all message formats present and future, WSDL allows using other type
definition languages via extensibility."

Rick,
As is typically the case a W3C Note does not imply endorsement by W3C.
Do you have a more up to date or normative document to quote on this point?
There is a delightfully Kafka-esque piece of prose in Chapter 3 of http://www.w3.org/TR/2003/WD-wsdl12-20030611/#eii-types which indicates that any schema language is supported if it is defined but then goes on to say that only XSD is defined. So, practically speaking, only XSD is supported. Or is my reading of the Kafka-esque prose letting me down?
