Re: [ddlm-group] Space as a list item separator

More specifically, CIF1.1 excludes square brackets as the first character in a non-delimited string.

Dear Herbert: as CIF 1.1 doesn't define lists, I'm not sure why you suggest that the example below is a valid tag.

Sorry something got lost in the prior message.  It should have

Dear Colleagues,

 Back to the question of commas.  If you accept the desirability of
having a CIF 1.5, commas in lists become very useful.  Someone with
a CIF 1.1 editor will be able to prepare a CIF 1.5 file for many
useful cases by doing all lists with commas and no embedded blanks
as long as they can make their lists fit on single lines.  In CIF 1.1

[[1,2,3],[4,5,6],[7,8,9]]

is a valid value for a tag, but

[[1 2 3] [4 5 6] [7 8 9]]

is not.


No, neither example is a valid CIF 1.1 tag.  CIF 1.1 explicitly excludes brackets as the first character of a non-delimited string.


Having the option of commas in lists will help to smooth the
transition for at least some people.
