Thanks for explain it. Is it good habit to make sure all the attributes for the element belong to the same namespace during loading? Or otherwise maybe attributes without namespace are easier for searching?
Helen >>> "James Clippinger" <[EMAIL PROTECTED]> 08/15/07 3:06 PM >>> Helen, default namespaces never apply to unprefixed attributes; attributes without a prefix are always in the no namespace. This is an XML specification (see http://www.w3.org/TR/2006/REC-xml-names-20060816/#defaulting) that has been carried through to XQuery. I don't know the reasoning behind that design decision by the recommendation writers and I personally dislike the differential treatment of elements vs. attributes, but it's how the language works.
