One of the problems with OWL built on top of RDF built on top of XML 
built on top of Unicode is that any problem with any of the layers bites 
sooner or later.

The use of namespace prefixes inside strings is well-established, e.g. 
in XSLT, but it causes difficulties - this is one of them.

I don't think that XML Schema uses these things exactly once, but then I 
  am not a schema expert, e.g. I never read part xml schema part 1, I 
just read part 2.
