I would be fine with disallowing all of [, ], {, and } from appearing anywhere in a whitespace-delimited data value. The [ and { do not at present cause
lexical ambiguity, but there’s something to be said for consistent treatment of opening and closing delimiters. Do note, however, that the opening [ of a list or { of a table is still required to be separated from any preceding value by whitespace. Thus _t [ depth_1[depth_1_still ] ] would contain an error at the second [. (There is still an error under the current spec or if only ] and } are forbidden in whitespace-delimited data values,
but it is at the final ].) This is still OK, though: _t [[depth_2] depth_1] John From: ddlm-group-bounces@iucr.org [mailto:ddlm-group-bounces@iucr.org]
