For each user provided PV name, Archive Appliance can (and by default
does) subscribe to several related PVs.  This is determined in the
policy hook script.

By default it will try to subscribe to additional PVs by appending .EGU
.HIGH and others to the user provided PV name.

This is where your addition channels come in.

I'm not sure what the state of DBE_PROPERTY support is in AA.  This
would help to reduce, but not eliminate, the number of extra channels
needed to also archive this meta-data.
