Updated 21 Dec 2021 by SP

replace input, output

Updated 30 Dec 2021 by MSM

stripped non-significant whitespace from result

Updated 01 Jan 2022 by MSM

replace expected result

Note that the input and the grammar are the same.

The expected result supplied in tests.zip cannot be right: it excludes the delimiter characters like ":" and ",", although they are not marked hidden in the grammar, and it marks whitespace as "s", not as "S". It appears to be parsing the input with a different grammar more like the current ixml grammar. It has been replaced by output thought correct. However, the old file has been left in place, in case of disputes over correctness.

The comment text "allcharacters,quotesmustbedoubled" looks like a possible error, but the comments in the input are also missing inter-word spaces.
