I just had a phone converstaion with R. D. Schaffer.

He expects the Identifier class to be used for identifying
all ATLAS identifiable objects. This implies that the muon
identifiers will have to associated with Identifier objects.
One implementations would be to for the muon identifiers
to inherit from Identifier.

The existing muon identifier implementation consists of
helper classes to build Identifier objects. My proposal
is to move this help into the specialized identifier
objects (e.g. MdtChannelIdentifier).

The structure of the muon (and other detectors) will be
specified in XML files. It is likely these will be outside the
identifier package.

RD emphasized that all subdetectors should follow the same
pattern for identifiers.
