Sure, but most people use HTTP URIs anyway for namespaces.

You can use any URI or any system you want with class="". The key is just 
to make it unique enough that clashes won't happen. In practice, names 
like "dc:title" are actually quite unique enough. But people can use much 
more unique ones if desired, all the way to full URIs.
