Online tool for OMR compliance

[Lasse Deleuran]

Nope, prolly a typo. Both should be 1.

That would also be my first guess, given that many OMR files have the "-1" qualifier. But then the following text is incorrect in the spec:

The <Optional Qualifier> is not mandatory and gets added only if there is more than one set that could be assigned the same <Set Number>.

The first set using a given number would be understood to never contain the qualifier however numbering should start with the oldest set and some investigation should be done in existing set databases.

Example:

Code:

6901 - Mobile Lab.mpd (Produced in 1980)
6901-2 - Space Plane.mpd (Produced in 1998)
