I'm saying it is an XML application language, first, 
by virtue of conformance with XML 1.0.  Then by virtue 
of infoset semantics, it becomes an interoperable 
platform language.  So yes, the semantic intent is 
to constrain an infoset, not the syntax of the instance. 

Data is portable.  Software interoperates.

I'd say it is a big deal.  It isn't the whole deal and 
that is why the "syntax only, keep your types to yourself" 
crowd can also go overboard.  I'm more concerned that 
platforms and XML are being conflated.  It's been hard 
as heck locally to get programmers to understand the 
differences, and as a result, real mistakes are made.

Oh, you were saying that XML Schema uses XML 1.0 syntax? That doesn't seem like a big deal given the hundreds of markup dialects built with XML. I meant that W3C XML Schema describes how to constrain an XML Infoset not a document written using the XML 1.0 syntax.
