The proposals on the table seem to me to raise several questions about element declarations which we haven't yet discussed here: * Should XML retain SGML's prohibition on multiple declarations for the same element (11.2.1)? * Should XML restrict the use of #PCDATA to content models of the form (#PCDATA), or of the form (#PCDATA | A | B | ...)*, as a way of avoiding the mixed-content trap (11.2.4) and/or of simplifying RE handling (7.6.1)? * Should XML prohibit the use of inclusion and exclusion exceptions in element declarations? (11.2.4, 11.2.5)? * Should XML prohibit content-model references to undeclared elements (11.2.4)? * Should XML forbid use of the '&' connector in content models (11.2.4.1)? * Should XML allow nondeterministic content models (11.2.4.3)?
