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

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.

Dear Colleagues,

�Back to the question of commas. �If you accept the desirability of

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.
