Schema discovery cannot discover what isn't said ;-)
Someplace in the schema, we need a good version identifier.
I think we might need the capability of specifying version in the
include statement (if the version dependency is important, but it
should be able to be left out when it is not important)

A dependency tree could be complex, and might be able to be avoided by
tightening the rules about how a module can be updated. OR we can try
to utilize some existing standards about handling dependencies.
