MOF24 — Delete the redundant package MOF::CMOFExtension described in clause 14.4

Delete the redundant package MOF::CMOFExtension described in clause 14.4

Every element shown in figure 14.3 (MOF::CMOFExtension) is a matching increment to a corresponding element shown in figure 11.1 (MOF::Extension). As far as these figures are concerned, the MOF::CMOFExtension package provides no additional capability beyond what MOF::Extension already provides. This would be sufficient to warrant deleting the MOF::CMOFExtension package. However, the resolution to issue 15827 involves adding a second association between Element and Tag that can only be expressed within CMOF because it involves a navigable owned association end, a capability that is specifically prohibited for EMOF per the resolution to issue 15820.
