Again you're confusing HTTP URLs with URIs.
Using URIs as identifiers allows lots of identification schemes other
than HTTP, in particular ones that are not based on DNS, or that use
DNS, but include a timestamp to address the concern of "losing" a domain
name (tag URI scheme).
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.
Yes, but unless they actually do use URIs, there's always the potential
of clashes. They may be unlikely, but they are possible -- that's one of
the reasons we have URIs, remember?
