I'm not a RELAX NG expert, but I am interested in this question, so maybe your or other experts can provide a bit more detail. What I see at http://relaxng.org/tutorial-20011203.html#IDAFLZR gives some of what I think people look for in W3C Schema lax validation, but not quite all of it. The difference I think I see is in the case where the attribute that does have a declaration (xml:space in the example at the link) gets its declaration from a separate schema document (in W3C Schema terms), perhaps for a different targetNamespace. The RELAX NG solution shown seems to require that a list of the elements to be validated be provided with the <anyName> wildcard in an <except> element. Consider a SOAP envelope: <soap:envelope> <soap:body> <po:purchaseOrder> ... </po:purchaseOrder> </soap:body> </soap:envelope> There are a variety of ways to acheive different effects using W3C XML Schema, but the schema that's officially published by W3C for the envelope has the body marked <any processContents="lax"/>. If someone comes along and writes a completely separate schema document describing the po:purchaseOrder, and passes both schema documents in on the API call to the validator, the envelope and the purchaseOrder will be validated together, and the overall envelope will be marked invalid if either the envelope markup or the purchaseOrder is in error. As I understand the solution proposed above, it would involve modifying the W3C-provided envelope schema to list <po:purchaseOrder> in an <except>. Does RELAX NG have another approach, or is this considered a non-goal? Certainly one always has the option of validating the container and the payload separately. Thanks!

For lax validation in RELAX NG you could take a look at the RELAX NG Tutorial by James Clark and Murata Makoto. Section 11 (Name Classes) handles this issue. http://relaxng.org/tutorial-20011203.html#IDAFLZR Greetings, Radu Cernuta 2007/2/6, Jeff Lowery <jlowery@m...>: This has got to be a FAQ, but no luck with googling: Trying to find a shorthand method to validate content using lax constraints in RELAX NG. I want something like this: #================= namespace foo = "http://www.w3.org/foo" qux = element baz {empty} # some element bar = element bar { anyLax* } #allow baz, bar, anyOtherElement anyOtherElement = element * - foo:* { # any elements not in this namespace attribute * { text }*, (text | anyOtherElement)* } anyLax = ( grammar {*} #all patterns )* #=========== Don't work, though. Only examples I've seen enumerate all the grammars by name in the schema. Doesn't appear there is wildcard of that type. _______________________________________________________________________ XML-DEV is a publicly archived, unmoderated list hosted by OASIS to support XML implementation and development.
