	Subject: [Megaco] Question about Descriptors in an Add Command

	 
	  Section 7.2.1 Add contains the text:
	 
	" All descriptors that can be modified could be returned by MG
if a
	   parameter was underspecified or overspecified.
ObservedEvents,
	   Statistics, and Packages, and the EventBuffer descriptors are
	   returned only if requested in the AuditDescriptor. "
	 
	The last sentence implies that the following list of descriptors
could 
	be included in the response if that same descriptor was included

	in the request with a parameter that was underspecified or
overspecified:
	     EventsDescriptor
	     SignalsDescriptor
	     DigitMapDescriptor
	 
	For the EventsDescriptor I believe "underspecified" would imply
the 
	"all events" wildcard.   What is less clear are instances of
underspecified 
	or overspecified in the following cases:
	
	[KJBII] Incorrect.  The "all events" wildcard is the same as
specifying each event separately -- each event in the package is present
and active in the Events Descriptor.  Under-specification allows the MG
to choose a value of a parameter from any legal value.
Over-specification allows the MG to choose a value from a specified
list.  These are clearly different concepts. 

	Descriptor        underspecified           overspecified
	
	Events                all wildcard                ?
	Signals               all wildcard(??)           ?
	DigitMap                 ?                         ?
	 
	We would appreciate some specific examples of the entries with
"?".
	 
	In particular, are there any instances where the
DigitMapDescriptor is required 
	in the response without it having been requested in an audit
descriptor?
	
	[KJBII] I cannot think of any examples of any of these
descriptors using under- or over-specification.
