Issue 17963: Figure 12-15 (MOF Model Equivalent …) p.284 - MOF Model Equivalent navigation and ownership incorrect (uml25-ftf)

Nature: Revision
Severity: Significant
Summary: Figure 12-15 (MOF Model Equivalent to Extending "Interface" by the Home" Stereotype) shows navigation only from the stereotype to the metaclass, but the paragraph just below it says the ExtensionEnd (the one opposite the metaclass) is a navigableOwnedEnd. Extensions were made navigableOwnedEnds in 2.3.  
Before that the spec explicitly said Extensions were non-navigable because the association owned them. This wasn't true, so Pete filed issue 9891 (ExtensionEnd description refers to old use of navigability) and it was corrected by making them navigableOwnedEnds.  
Presumably the figure should show navigation in both directions and use the dot notation to show which end is owned. 
A constraint could be added to Extension that its ownedEnd is a navigableOwnedEnd.
