I prefer P to P-prime for completeness, esp in dealing with unicode. I prefer P-prime to F or GP for completeness, but find F and GP tolerable because they are at least reasonably consistent with P and P-prime, esp. in folding lines that contain various patterns of backslashes. Personally, I find GP slightly preferable to G, just as I find F slightly preferable to F'. I agree with Herbert that a means to elide the elide character (F or GP) is technically preferrable to context-sensitive elision (F' or G), even though the two approaches have equal expressive power. If nothing else, GP and F will be slightly easier to process, and a bit more friendly to reformatting. Also, although I do not share Herbert's confidence that CIF will need or want to adopt a P-family syntax in the future, I do see enough chance of that to accept future consistency as a reasonable factor to consider, though I assign it much less weight than Herbert does. Considering technical factors only, I prefer F / F' to G[``] / G'[``] because the former do not obligate us to add another character to those that cannot start a whitespace-delimited value. (That consideration influenced my suggestion of "'" and '"' as delimiters to use with G.) Any of these F-family proposals is acceptable, however, and I would prefer any of them to P', which in turn I prefer to P. Regards, John -- John C.
