[sc34wg3] TMCL / CTM issue: ctm-integer

Hi all,

CTM should define a special datatype "ctm-integer" to satisfy TMCL's
need to specify an unconstraint upper limit:

     topic has-occurrence(tmcl:comment, 0, *).

Now I wonder if it is wise to derive the datatype from xsd:integer
since xsd:integer has an infinite value range. What value should
ctm-integer have? Infinity +1?

Wouldn't it be more logical to derive from xsd:int and set the value
of ctm-integer to xsd:int's maxInclusive +1?

Or has ctm-integer no explicit value, just the notation "*"?
