Interesting, I wasn't aware of it and I am not sure if I understood it
completely. :) Anyway, isn't this solution more less equivalent to our
INF-solution: We have to check somewhere if the value is
'*'^^ctm:integer which would be the same as checking if the value is
'INF'^^xsd:double (which would be the only possible datatype !=
xsd:integer in TMCL-constraints)? The only difference would be that
all xsd:integers are valid ctm:integers, which is not possible with
Btw, TMQL uses '*' as wildcard, so we'd have a mismatch between the
datatypes TMQL recognizes natively and those datatypes which are
recognized by CTM natively. Something we wanted to avoid.
