Re: Draft PAR for further comment

No where, in either the purpose or the scope, does the PAR provide direction
to be compatible with the work of the SID group. Once again, I reiterate my
point that there should be a single successor to VHDL 1076 as we know it
today. Neither the SID nor the OOVHDL PARs address the compatibility
issue. I cannot support either PAR until this issue is addressed. I would
prefer to see the two groups merged into one (two technical committees can
continue to work the different areas, but the result is one 1076 follow-on and
not two dialects). However, at minimum, the PARs need to address the issue.

Victor, this issue needs to be discussed at the next DASC steering
committee meeting. When and where is it?
