Does that mean the below set of schemas are valid? Does ID attribute =
have applicability only with respect with the XML representation and not =
with the includes?
Thanks

There's no conflict.  The xsd:include is not the same as an XInclude 
include.  xsd:include 'includes' the schema components that belong to 
the *parsed* included schema document.  It doesn't 'include' the xml 
representation of the included schema document, so the DTD for schemas 
is not applicable.  As far as I can tell, the id attribute doesn't 
constrain the schema components (only their XML representations).
