I understand what this passage says, and I have coded it as such, but 
the last sentence in 7.6.5.2 can be somewhat misleading:

"Note that an empty list is a possible valid response (whether or not a 
wildmat is specified) and indicates that there are no such groups."

Perhaps this should say: "... indicates that there are no groups 
matching the selection criteria which have descriptions."

Sorry, I missed that.  Do we really want two ways to say the same thing 
(HDR ALL and ":"), ":" seems sufficient.  But I'm not going to argue.
