SYSMLR — The XMI file isn't conform to the pdf specification for Refine and Trace stereotypes

The pdf is that Refine and Trace have 2 specializations but have only one generalization in the xmi file
(http://www.omg.org/spec/SysML/20150709/SysML.xmi)

Some elements extracted from the pdf and the xmi

16.3.2.3 Refine
Description
The Refine stereotype specializes UML4SysML Refine and DirectedRelationshipPropertyPath to enable refinements to
identify their sources and targets by a multi-level path of accessible properties from context blocks for the sources and
targets.

The Trace stereotype specializes UML4SysML Trace and DirectedRelationshipPropertyPath to enable traces to identify
their sources and targets by a multi-level path of accessible properties from context blocks for the sources and targets.
