Do you have them separated out merely for ease of maintenance, or do
you anticipate using different contents for the individual files?

The obvious alternative would be to avoid the machinery of "define"
combination, and simply use externalRef to bring in the element patterns
directly.  This is somewhat more streamlined.

I don't see that it's any better or worse to have to ref common
subpatterns than to have to specify a common base type.
