nit MXF_COMMON_OPTIONS ?
feels more comfortable to me when grepping the code etc.

Isn't 07h the largest valid value (G.2.3)? Or do I misunderstand the
constraint values? (AVOPTION not my strong point)
I thought numeric options were deprecated these days in favour of more
understandable string values, or are the string values also too obscure
to be useful in this case? (Just wondering what the current protocol was
on this nowadays, not a real concern in this case)
