I don't think that "average developers" need to worry about namespaces. It
is quite simple to build powerful, useful applications without them. I
mean if you are implementing RDF or XSL then you need them, but short of
that, I wouldn't bother.

Actually, this problem is very RARELY encountered. If you are building a
typical one-organization application then what are you doing with "other
people's tags" in your documents? I mean, if you are writing typical
software, it will choke and die when it comes upon tags it does not know
about.

You don't need namespaces for that. Just create a "liters_quantity"
element type and include it in your various DTDs with parameter entities.
