so one thought about this.

I don't know how functional this is in terms of xml namespaces - but it
would be great if there were a way of subclassing namespaces.

so you had a base package namespace
and then you had rpm and deb subclasses that use the base package
namespace for common things.

that way people parsing the file could write their parsers to the base
namespace and then to the other items in the deb and rpm subclasses.

So we'd still need to hash out the common areas for the base name space
and maybe as revisions and versions go forward be able to move more
things into the common namespace.
