* SAX.c testXPath.c valid.c xmllint.c include/libxml/valid.h: allow to inherit attributes from the DTD directly in the tree, this is needed for XPath and can be a useful feature. Inherited namespaces are always provided at the tree level now * test/defattr* result/defattr* result/noent/defattr*: added a couple of tests for this feature (XSLT being the prime user). Daniel
