I want to ask what justification there is, if any, for ruling out empty
PEs? I don't remember discussion of this point clearly (though I do
remember shock when the rule was pointed out).
This seems like a very bad idea, as Terry's desire for add entities in
is very reasonable.
Is this fallout of the weird SGML interleaving of entity structure and
content model parsing?
