Re: [ddlm-group] Relationship asmong CIF2, STAR,CIF1 and Python. .

Hi Herbert,

Your list of objectives is consistent with my understanding, and I would
only add in addition to item 1 that there were some extensions specifically
to facilitate dictionary merging and maintenance.   Perhaps these are lumped
into the context of DDLm, but these are in some since separate from the
methods support.    I believe these changes for merging have little impact on
syntax issues, but Brian may want to comment on this issue.

I would strengthen item 4 in that I believe the original idea was to fully
support existing syntax and semantics for archived CIFs.  I think this goal
has been bent as the conversation has drifted into "improving" the syntax.
