Why a single schema?

Seems like there could be different schemas depending on the context.

For example, a SOAP intermediary by want to validate the SOAP header 
blocks, but use <xs:any> for the body.  The endpoint may want stong 
validation for the body before it does a non-safe operation (like debit a 
bank account).

Perhaps rddl:purpose="..." can be used to find the appropriate xsd that you 
need, assuming a set of xsd's.

(I kind of like the RDDL concept [1]).
