Namespaces seem like a nice >lightweight mechanism to allow easy reuse of standards. The whole point of namespaces is to enable me to distinguish my FOO from your (or SMIL's) FOO. That's all.

People who have a problem with namespaces seem to expect them to do more than they are actually intended for. James
