This is one of the reasons that I strongly disagree with requirements, for
either RDF or Topic Maps, that subjects (or their equivalents) have to be urns
or some kind of address.   They ought to be able to just be data (like
strings). If you want machine-readable terms for inference or hyperlinking,
fine, use them.  If you want text phrases for humans to read on a display, use
strings ( or data: urns).  Don't restrict the map creator.
