Currently making a parser for PGN files. And wondering if there is any practice of using commentary in Tag pair section, like:

[Event "Tournament X"];hosted once a year

[Event "Tournament X"]{hosted once a year}

Has anyone seen such PGN? Is it used? Cause I couldn't find no such clause in PGN standart that forbids such comments. Or it's me that's just blind...

The first example is invalid in PGN, please don't do that. Your second example is also invalid. We don't put comment to the same line as the header.
