Thank you very much, Chris. I stand corrected.

Allow me to re-state my earlier post ...

//

All,

Fyi ...

During the OntoIOp team meeting of 15-Aug-2012, the issues raised by
FabianNeuhaus and TillMossakowski concerning definitional extensions
in Common Logic appears to be an unintended consequence of the
decision to make CLIF an unsegregated dialect. Allowing a segregated
dialect of CLIF would get around these problems.

FabianNeuhaus and TillMossakowski, supported by JohnSowa and
MichaelGruninger, suggested that we should use this as an argument to
propose a modification to the CLIF dialect of Common Logic (as
currently defined in an appendix of the CL ISO standard,) to allow for
the use non-discourse names in definitions and, hence, to make CLIF a
segregated, rather than non-segregated, dialect of Common Logic.

For those who are interested ...
Till has since started the thread on the [CL] mailing list and it is
being actively debated - see: thread under "[CL] Definitional
extensions in CLIF are not conservative" -
http://philebus.tamu.edu/pipermail/cl/2012-August/thread.html#2448

... anyone who would like to contribute to that discussion, please
consider doing so on the [CL] list ( ref.
http://philebus.tamu.edu/cgi-bin/mailman/listinfo/cl ).

Modification to Common Logic per se is not required to implement this.
