RE: [xml-dev] Lesson Learned: Use namespaces for both markup anddata

["Paul Spencer" <xml-dev-list@boynings.co.uk>]

I deal with many document types that have an envelope within which is both
addressing information (and perhaps other things such as a digital
signature) and a single payload element containing data. In other words, the
payload data would be a well-formed XML document on its own with its own
root element, but this is embedded in something else. In this case, it is
common to declare a default namespace in the embedded element that is
different from the namespace(s) of the envelope. SOAP-based web services
also come to mind.
