I came in late on this discussion, so excuse me if this has already been mentioned. One thing that could suffer due to hiding namespaces is code reuse. In particular, any code that processes a particular element/attribute based on URI + local name won't be able recognize that element/attribute if the namespace is hidden. Whether this is a serious problem is not clear -- a similar problem already exists for code designed to process a given complex type, regardless of the name of the element. Thus, the general way to write such code might be to always require its initialization with the correct name(s). -- Ronald Bourret Programming, Writing, and Training XML, Databases, and Schemas http://www.rpbourret.com
