Fix odd validation on constraint in mensural module

[rettinghaus]

After some more attempts I finally was able to fix the ODD.
closes #789

@rettinghaus thank you! Could you add the scope of this PR (mensural) to its title?

@martha-thomae Maybe you could have a look (or someone else from @music-encoding/ig-mensural)?

[martha-thomae]

Great! Thanks, @rettinghaus!
Yes, I might be able to check this over the weekend. If anyone else from the @music-encoding/ig-mensural can see it earlier, they are welcome to do it :)

Hopefully, I understand the issue correctly:
As far, it seems the validation errors in the older version are fixed. I built the schema and tested the constraints. It seems they work fine now.

I only recognized some issues concerning the customization path in this branch... just to mention it after @bwbohl fixed the windows situation lately. This hasn't anything to do with this, I was just wondering...

[bwbohl]

you mean the changes to build.xml are not present here and you would need a rebase of this branch in order to build on your windows machine?

[annplaksin]

@bwbohl I don't think so, your changes are there. As kind of an uneducated guess, I am not sure whether cbc7901 might have to do something with it. It broke again because of the paths. Should I make another issue for this or should I wait with testing it again when you are finished with whatever you are doing now? It might be more useful to not highjack this pr too much...

[rettinghaus]

@annplaksin That's a different issue that should have a separate PR.

[martha-thomae]

I have reviewed this PR and everything seems ok. Thanks, @rettinghaus!

I do remember that @kepper said that he was going to look into this issue and he had a draft PR, in case he wants to take a look too. But, from my side, everything seems fine and I would merge it!

many thanks everyone :)
