This may be important if parsing an XML document using DOM - for example, one may want to "place" elements that are always/often accessed (such as primary key values in relational database terms) near the top of an XML document, or near the top of a content model within an XML document for performance purposes. (But since a tree for the entire document needs to be built anyway, this may not buy you much in terms of performance - just thinking out loud). Joe Chiusano Booz | Allen | Hamilton "Bryce K.
