Um, yes, you are right.  DeclSep was introduced in the second edition,
and I hadn't noticed that it was used in the extSubsetDecl production.
This doesn't really solve the problem, since it doesn't cover this:

  <!ENTITY % e "> <!--">
  <!ELEMENT doc EMPTY %e;
  -->

which appears to be merely invalid.
