Re: Issue: references to an external grammar

[James Clark <jjc@jclark.com>]

Another possible approach to this is to allow <grammar> inside <grammar> 
and add a new <export> element.

<grammar>
...
<grammar>
  <export name="foo"> p </export>
  ...
</grammar>
...
</grammar>

is equivalent to

<grammar>
...
<define name="foo">
  <grammar>
     <start>p</start>
     ...
  </grammar>
</define>
...
</grammar>

except, of course, that you can multiple exports in a single <grammar>.

You wouldn't be able to have both an <export> and a <start> in the same 
<grammar>.  An <export> inside an <include> would replace a <start> in the 
included file and vice-versa.
