I feel a bit like a bonehead. A few minutes after sending the
message I fell victim once again to Kal's cleverness. :-)

In TM4J there's a method

    org.tm4j.topicmap.TopicMapUtils.getDisplayName(Topic,Scope)

which I will simply use rather than writing my own. Its description
is thus:

    Returns a string which may be used as a display name in the
    specified scope. If a variant name with a parameter of
    'display' exists in the specified scope, then that variant's
    name string is returned. Otherwise a base name in the specified
    scope is sought and if found, then the base name string is
    returned. Finally a base name in the unconstrained scope is
    sought and that name string returned. If all of these searches
    fail, null is returned.

This is basically what I was thinking, and it's nice I don't have
to reinvent this wheel. (thanks Kal)
