[TYPO3-mvc] mm relation with attributes

If your "mm-table" has some additional properties, you most likely can 
also give the relation a name and thus convert it to a real object 
rather then a "hidden" intermediate table. And by converting it to a 
real object you can easily deal with in forms etc.
So your domain structure would in the end look somewhat like this:

SpecialField <-> FieldOfActivity <-> Company


The "FieldOfActivity" object would have at least these three properties:
- specialField
- company
- percentageOfInterest
- ...


Your "Company" and "SpecialField" objects should use a IRRE relation 
with "foreign_field" configured for the fieldOfActivity table. The 
FieldOfActivity object could either have a select box or a group field 
(whatever you prefer) for company and specialField.

That's at least how I would solve it and what makes most sense to me.
