Agreed...

Yes, it would be a string or a uri (also a string).  I find I haven't use
used this method much, since if it's a uri I usually want to build a
hyperlink for it, so I have to know whether I've got just data or a uri
anyway.  So that method could be ditched.

Will do, thanks.

Thank you, Danny.

Sure, but it's not as clean as the core.  It has a lot of functions like
addTopic(map,topic), among other things.  It grows from a decent base in a
sort of adhoc way as I need something - at some point I will need to get it
under better control.  tm_utility is especially in need of refactoring since
it contains functions to build topic map components and handle topic maps,
mixed together with debugging things and other utility routines.
