Even more elaborate than Scott's response, many other properties (such as
rdfs:label) use rdfs:Literal as their range, but in fact the most common case
is to use string literals as their values. So while in the case of SKOS, it
should create untyped literals, in most other cases it shouldn't. We could
certainly hard-code something in TBC to treat the SKOS properties differently
from others.
We have recently (for 3.5) added support for the type rdf:PlainLiteral, which
will create untyped literals. So you could change your local copy of the SKOS
namespace to use this as a range and it should work.
