[tmcl-wg] Another TMCL use case

[Dan Corwin]

My WORDS command language uses topic maps for storage, and 
changes them under interactive inputs or batch files.

I hope to use TMCL in this system, so WORDS is another use 
case for it.  But I cannot tell from current requirements 
if TMCL will work fast and flexibly enough for editing, 
or if the data to validate must already be within a TM.

Unsure on such issues, and on when TMCL might appear, I went
ahead on a private WORDS spec and coding plan to incrementally 
pre-validate requested TM updates.  Here's what emerged:

This design gives a coder's view of a constraint language.
It may be instructive, or it may need some rethinking.

Either way, your comments and suggestions would be welcome, 
especially on any specific parts of this design which seem 
useful to TMCL or off-track.  Thanks.

Cheers,
Dan Corwin
