Since your conclusion is based on your assumptions, which you yourself say 
are based on conjecture, it's hard to respond meaningfully.

I don't have good statistics on this, but I sure do see a lot more schemas 
in the real world than you seem to. Most of the applications I see that 
need datatypes together with XML are using XML Schema for this. Most of 
these applications use simple schemas, basically the "DTD+Datatypes" 
subset, though there are also quite a few uses of groups and some other 
features. Database applications are an important class of applications 
where datatypes matter, and it's no accident that database vendors are 
strongly behind XML Schema.

Does anybody have real data on the market penetration of XML Schema? I 
think that vendor support for XML Schema is clear, but if Adam is right, 
that's irrelevant. Vendors seem to believe that people are actually using 
XML Schema, too. Are they right? Do we have real evidence on this question?
