AMSM — AMS_Property template

In the spec the AMS_Property template have been used several times; it has been used in the PIM for instance as: AMS_Property<AMS_StdState,ST_NOSTD> or AMS_Property<AMS_StdMechanism,MS_NONSTD>. Now, it could be useful to always use the same convention to define the names of such “non stardard” enumeration values (such as ST_NOSTD or MS_NONSTD) since sometimes in the document it is used ST_NONSTD instead of ST_NOSTD, or MS_NOSTD instead of MSNONSTD and so on…In this way it would be easier to catch these little inconsistencies. For instance in the diagram 7.16 it is used MS_NONSTD instead of MS_NOSTD... but it is just an example since this kind of error can be found in various parts of the document.

Generalize the use of *_NONSTD
