A 'sparse' table containing service detail information for
installed and (possibly) active services on this host system,
augmenting the basic entries in the 'xcmSvcMonServiceTable'
of the XCMI Service Monitoring MIB.
Usage: UNLIKE the 'xcmGenOptionTable' in the XCMI General MIB
(which is a unique exception), this table of 'dictionary-based'
service details is used with DIRECT create/update operations.
