If a reasoner supports string and supports the facets with which Name 
and/or NCName are defined, then it should be strongly encouraged to 
support these. I tend to agree that they are not useful for typical 
semantic web apps, but in as much as the W3C should form a coherent 
whole, we should encourage SemWeb implementators to not wilfully not 
implement a part of some other spec.

Jena supports this too; I wouldn't be surprised if the Pellet support 
depends on the Jena support.

What about people without a google account?
