I'm currently writing an SGML Open catalog parser in Python for inclusion in a set of XML parsing tools I'm building at the moment and I'm also writing a SAX EntityHandler to interact with the catalog parser. However, those SGML Open catalogs allow one to specify things like ENTITY my-entity "sysid1" ENTITY %my-entity "sysid2" Which causes me grief, since SAX does not distinguish between these two kinds of entities so there's no way to tell whether the entity name given in the call to resolveEntity belongs to a general or parameter entity. If XML does not have separate name spaces for parameter and general entities this won't be a problem, but as far as I understand the 1.0 spec, the name spaces are separate. One way to solve this might be to use a preceding "%" in the entity name to signal parameter entities. Since "%"s are not allowed to start entity names this should be sufficient. Clients that aren't interested in the difference can just disregard the leading "%". BTW: This is actually the first "problem" I've had with the SAX specification. IMHO it is very clear and includes exactly what is needed. Well done! :) -- "These are, as I began, cumbersome ways / to kill a man.
