usdPppoeProfileSetMap
1.3.6.1.4.1.4874.2.2.46.1.1.1.1.2
A bitmap representing which objects in this entry have been explicitly
configured. See the definition of the UsdSetMap TEXTUAL-CONVENTION for
details of use.
The INDEX object(s) and this object are excluded from representation
(i.e. their bits are never set).
When a SET request does not explicitly configure UsdSetMap, bits in
UsdSetMap are set as a side-effect of configuring other profile
attributes in the same entry.
If, however, a SET request explicitly configures UsdSetMap, the
explicitly configured value overrides 1) any previous bit settings, and
2) any simultaneous 'side-effect' settings that would otherwise occur.
Once set, bits can only be cleared by explicitly configuring UsdSetMap.
