[sc34wg3] Scope support in Ontopoly

[Steve Pepper]

I wasn't aware that this couldn't be expressed in TMCL.

That would appear to be a major omission. I can't imagine a multilingual topic
map for which one would *not* want to have an enforceable policy regarding which
*specific* languages should be used for which particular types of name and
occurrence.

Will you register this as a TMCL issue?

Steve

| This is not expressible with TMCL today. You can say
| 
|    language isa tmcl:topic-type.
|    # define 5 instances of language
| 
|    topic-type has-occurrence(field, 5, 5).
|    field has-scope(language, 1, 1).
| 
| but you cannot require the five occurrences of the type field to all
| have different instances of language in their scopes, except by using
| a user-defined constraint.

| 
| It is not easy to avoid that conclusion, no.
