Use naming pattern: Command / Device / command.
Situation: instances of patterns may be identified in SAREF, but sometimes only partially, and with naming heterogeneities.

Proposal: There should be a clear classification/hierarchy that is common to saref:Command, saref:Device, saref:Function. And saref:Property. The current relation between commands and devices is partial and misleading.
