Yes - I was assuming that the VRML was describing something that it was intended
to make; that is, that it had been created with that in mind. It's easy to
throw the extra information away, and to avoid dodgy constructs, if you are
working with that intention.

Of course, the STL format could take the wooden spoon for the worst-designed
data structure of all time. If people had included the topological information
in it when it was specified, think how much easier our lives would be now.
