Re: [ddlm-group] Simplifying string handling in CIF2

I disagree.  We are already committed to continuing to support both
CIF1 and CIF2 data sets in the future, so there is every reason to
deal with both CIF 1.1 string syntax issues _and_ CIF 2 syntax issues
in our discussions.

In any case -- to avoid any misunderstanding and have us all working 
from the same base please send whatever proposal we are discussing as 
one self-contained document
