I think annotations about attributes could be added in the form of co-attributes in a different namespace. In any case, I meant 'attributes only' as a goal, if it's practical. If it's not practical, we'll have to insert some elements. Here's one way co-attributes might work: This document: <E xmlns:foo="https://example.mil/foo" id="A1" a="1" foo:bar="CRM_114" /> Would be decorated to look like this: <E xmlns:foo="https://example.mil/foo" xmlns:a="http://example.org/decorations_for_unqualified_attributes" xmlns:qa="http://example.org/decorations_for_qualified_attributes" a:id="xsd:ID" id="A1" a:a="xsd:text" a="1" qa:foo.bar="something_else" foo:bar="CRM_114" /> The trickiest part is aliasing qualified attributes as prefix.NCName , and using separate namespaces for qualified and unqualified attributes. -Wayne Steele _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
