In 5 minutes, things changed on me.

I just tried to create an instance in XML Spy and the software could not 
find the types unless the types were prefixed (as they were in 
0p65).  Since 0p70 uses a common reusable included file of declarations, 
these declarations cannot have prefixed type names because every document 
type uses the declarations.

So, I can understand if people are using XML Spy to test these schemas that 
the target namespaces were removed ... but I thought we needed them in 
there to distinguish the vocabularies.

As I said, MSV works just fine without prefixing the type names.

My gut feel is that MSV is correct and XML Spy is incorrect because looking 
at examples in XML Schema books I don't see why the types need to be prefixed.

Can anyone shed light on this?

Thanks!
