Thanks. Other pointed me to that, too.
The rules and meta-rules for UCD building imply that each UCD fills a
niche in a larger semantic ecology. Each new UCD causes a potential
challenge to all previously declared UCDs or lists or namespaces of
The tool I was suggesting would not only test a single proposed UCD
against the syntactical rules, but also test a list of same (e.g.,
representing a namespace) against the rules for building lists of
UCDs. I suspect that the notion that two namespaces cannot contain
identical UCDs (or more stringently, was it identical "words"?) will
fall by the wayside, but if not, it would prove useful - almost
mandatory - to have a tool to vet two lists against each other, or
for instance, a newly proposed list against all previously registered
Which is to say that the choice of rules for assembling lists of UCDs
is not a completely free design parameter.
