Hello,

the use of the "source"/"target" elements can be a bit confusing because not all of the elements contained thereing actually refer to constraints on the association. An association always requires a source and a target. The "mandatory" information affects the source/target types more than it affects the association itself - e.g. if the "source" is mandatory, then no instance of the target type can exist without having an association linking to it from an instance of the source type. It is the same with "many", e.g. "source" => "many" = true means that multiple instances of the source type can have associations to the same instance of the target type.

The effect of "mandatory" is quite extreme and since there is no way to differentiate a "should" and "must" mandatory state (like you can do with mandatory / enforced-mandatory for properties) it is usually kept to "mandatory" = false.

Axel
