Conceptually, we include an external grammar once (without name
collisions) and then reference to more than one named patterns in
the external grammar. Ideally, the syntax should directly reflect
this semantics.
Here is a strawman proposal. Rather than
...
<withGrammar href="u"> <ref name="p1"/> </withGrammar>
...
<withGrammar href="u"> <ref name="p2"/> </withGrammar>
...
How about
<div withGrammar="u">
...
<externalRef name="p1"/>
...
<externalRef name="p2"/>
...
</div>
?
Cheers,
Makoto
