SYSMLR — Cannot navigate and represent deep nested defining feature in a slot

As discussed in the RTF plenary on Sep 12 2016 the ability to
navigate and represent deep nested defining feature not directly owned in the classifier of that instance would largely simplify the construction of instances specification trees.

Consensus was reached in the plenary.

There is a potential problem with UML which says that slot defining feature is a feature of that classifier.
Michael Chonoles volunteered to work on this on the UML RTF side.

This Issue was not resolved in this Task Force and was automatically deferred to the next Task Force
