The commented out string is considered by dt-schema to be "not a regex", but regex101 thinks it is... Maybe dt-schema does not support named match groups, but they are the only way that I could trivially find to make this somewhat manageable. Either way, it is permissive so it allows combinations of "M", "MpM" & no number.
