So how far do you take that concept?

Agree that it's a very viable option, 
for the immediate problem that I'm 
faced with.  However, let's say there 
are other schema's that will be 
developed in the future that will 
use this same 'vocabulary' but instead 
of using the elements in schema D, I only 
need a subset of them plus a couple
others for a new schema.  Would need
to break the subset of common elements
down more.

You could take it to the point where 
every element is in it's own schema.  
The resulting messages are just 
comprised of of the appropriate
included single element schemas so 
that this issue wouldn't rear its
head again as schemas are embedded
in other schemas or re-packaged.
 
Sure it's overkill, but if you plan 
to extend the message set, it's 
possible to run into this situation
again and again.

Thanks for your input!
Cheryl

You should package up all common definitions in a schema D. Include 
schema D
in A and B. When C includes A and B, you will not get your duplicate
definition error, because there is only a single source (schema D) for 
those
definitions.
