comments in transformation rules

[widc]

It would be good to have to the possibility to comment out some portion of the transformation rule.

The commenting prefix of the Manchester syntax ("#") is not working in the transformation rule - Generation of axioms terminates prematurely with the "Encountered <LOCATION_SPECIFICATION> # at line ..." error message.

Rationale:
I have several similar worksheets in an Excel file, and a specific file with the transformation rule for each spreadsheet. It is expected that the structure of the worksheets will converge in the future - new columns will be added to the worksheets where they are missing so far. Therefore, I'd like to have prepared but commented-out parts of the rules which are not applicable yet for the given worksheet.

Note that MM will drop sub-expressions with missing values so comments may not be necessary.
