Agreed to take an errata to disallow %WSP*; on its own in places where it is currently allowed but %ES; is not allowed.

But we do allow character class entities like %NL; %WSP; %WSP+; and... problematic: %WSP*; I claim if you don't allow %ES; you should not allow %WSP*; because it matches zero-or-more, allowing an empty-string to match in principle. Leaving off WSP* only eliminates the zero-characters option, as WSP+ is available. There are probably other places in the spec that have this same issue. Basically, anyplace that %ES is disallowed but the other character class entities are allowed. -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com -- dfdl-wg mailing list dfdl-wg@ogf.org https://www.ogf.org/mailman/listinfo/dfdl-wg Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
