Summing up this monologue, just for the record :-)
And I still don't know if there are any better solutions.

Using the entity, I lose error reporting line numbers inside the entity
(using jing/xmlbuddy), and when I'm still coding the entity this is a
nuisance.
But the entity solution also allows me to include a pattern without
enclosing it
within a grammar, thus allowing easier access to global defines as well as
the
defines of the grammar containing the entity reference.

Using the include element, error reporting is good. But I don't like
splitting a structure across two files just for the mechanics of the schema
language. I like such splitting to reflect a separation of logic. (And in
the actual schema I was working on, not this demo, I ended up using two
entities.)
