Even so, people have been solving these sorts of problems without
namespaces for years (i.e HL7 initiative). In order to exchange documents
in healthcare it is probably NOT necessary to mix elements from different
document types *blindly*. That's all namespaces help with.

If you know in advance what element types must be mixed in a document of a
particular type then you can just choose names that do not clash (or use a
simple prefixing convention).
