Thanks, I should have looked at the documentation more before posting. I see what you're talking about now and I think I might have an explanation of what's going on. The error_log says: --------------------- 4:0:ERROR:RELAXNGV:RELAXNG_ERR_ELEMWRONG: Did not expect element para there 4:0:ERROR:RELAXNGV:RELAXNG_ERR_ELEMNAME: Expecting element example, got para 4:0:ERROR:RELAXNGV:RELAXNG_ERR_ELEMNAME: Expecting element bridgehead, got para 4:0:ERROR:RELAXNGV:RELAXNG_ERR_EXTRACONTENT: Element para has extra content: text 4:0:ERROR:RELAXNGV:RELAXNG_ERR_ELEMNAME: Expecting element annotation, got para 4:0:ERROR:RELAXNGV:RELAXNG_ERR_CONTENTVALID: Element article failed to validate content --------------------- But my libxml2 version is 5, which I think means that schematron isn't supported. And the docbook.rng contains some embedded schematron. From the DocBook 5 documentation: --------------------- If you want to validate against the DocBook 5 RelaxNG schema, then you have to find the right validation tool. The DocBook 5 RelaxNG schema includes embedded Schematron rules to express certain constraints on some content models. For example, a Schematron rule is added to prevent a sidebar element from containing another sidebar. For complete validation, a validator needs to check both the RelaxNG content models and the Schematron rules. --------------------- Does that make sense? thanks, --Tim Arnold _______________________________________________ XML-SIG maillist - XML-SIG@python.org http://mail.python.org/mailman/listinfo/xml-sig
