I found in the text for the test files:
A single space after the tag of a structure with no payload.
For example, "1 CHAN " and "1 CHAN" are equivalent.
This is wrong. The spec says:
Line = Level D [Xref D] Tag [D LineVal] EOL
So, if there is no LineVal, there is no space following the tag.
Please correct, and eliminate this text.
