Many thanks for the response Dejan. This is pretty much what I had
expected - I do understand the pragmatic reasons behind these
decisions, but perhaps I can just summarise my concerns ..

1) If people are expected to make independent implementations of a
   langauge, they are much more likely to work correctly if the
   the language is defined by a written semantics, rather then by
   a reference implementation where people have to guess the
   significant parts of the semantics by reading someone else's
   code (for example, "does the order of these elements matter"?)

2) Certainly in the system config area, people at many different
   levels of skills will be expected to make contributions to an
   overall configuration, and we have identified the difficulty of
   learning to use the language as a major barrier to the uptake.
   Misconfiguration due to language confusion is also a major
   source of configuration errors. Hand-writing CDL is going to
   be significantly more difficult than the languages that we
   have considered previously.

I would like to have seem a simpler language which standardised on
the well-accepted basics, and left out (or made optional) the more
"research"-oriented" features which could be layered on top later.

I'll definitely keep you in touch about the workshop outcome, and
I'll probably have more questions before then ... :-)

Many thanks
