The strategic outlook: a summary
If you don’t have to mix vocabularies, no problem
If you do, not having a namespace makes life difficult
You can’t have a prefix either
... So you can only mix with tag sets that do have namespaces ...
A “good citizen” XML document markup format will have a namespace
This avoids problems and makes things easier for tools and developers
Facilitates use in mixed environments, enables adoption in new applications
You can still avoid prefixes when you want (as long as everyone has a namespace)
