Re: RE: Compelling use case for XML Catalogs?
Costello, Roger L. scripsit: > Does XML Catalog have the ability to express this: [snip various conditional things] No, of course not. Catalogs can only express one thing: when you see this URI, use this other URI instead. (And ditto for public identifiers.) > If it does not, how would you avoid a spoofing attack? You can't. If you want to make sure a document that you have received validates against a DTD of your choice, convert the DTD to a RELAX NG schema and validate against that instead. Because you get to specify the schema to validate against, this is safe. In general, XML validation asks the question "Is this document self-consistent?" because the DTD is really part of the document. XSD validation (at least with typical XSD tools) asks the question "Is this document consistent with the schemas it refers to?" RNG validation asks the question "Is this document consistent with this schema?" IMHO the last is the most interesting question. -- But the next day there came no dawn, John Cowan and the Grey Company passed on into the firstname.lastname@example.org darkness of the Storm of Mordor and were http://www.ccil.org/~cowan lost to mortal sight; but the Dead followed them. --"The Passing of the Grey Company"
