That's not quite what I suggested. I suggested that a process (XSLT or
otherwise) could be used to produce an _actual_ DTD document which could
then be used to obtain character entity references in a conformant manner.

For example,

<!DOCTYPE x SYSTEM "edml:http://example.com/entities.edml">
<x>&ent;</x>

Where http://example.com/entities.edml contains:

<entities>
   <entity name="ent">foo</entity>
</entities>

Could be used with any SAX parser today, given an appropriate
EntityResolver.

Alternatively, a parser could support the edml: scheme directly, as an
optimization.
