[wsrp] Types for names

It came up on the Interfaces SC yesterday
that we ought to tighten up the fields where names are defined as a number
are currently typed as xsd:string and xsd:QName is often more appropriate
for avoiding name clashes. A scan of the spec suggests the following fields
be changed:

ItemDescription.itemName? -> text
currently suggests this be a URI ... would a QName be better?

PropertyDescription.name

Property.name

ResetProperty.name

NamedString.name? -> gets used for
mimeHeaders and form parameters, but a QName is allowed to have a missing
prefix

I am not including the ResourceList
related name fields as those are highly localized and therefore should
not suffer from name clash issues (at least none that the Producer can
not completely manage).
