Having started to implement TMCL with regards to schema-driven-form
generation in Topincs, i was surprised by the new datatype. Then
again it makes sense if you want to specify an unlimited upper
boundary and none of the xml schema datatypes is helping out. Would
it be an option to simply handle it the following way and thus
eliminate the need for a special datatype:
1) No statement about the upper limit defaults to upper limit =
2) No statement about the lower limit defaults to lower limit = 0.
This would be in a similar spirit as interpreting the empty scope as
unconstrained and not requiring a special topic "Unconstrained" for
that very purpose.
