It would be very helpful if the draft made plain that it is 
discussing only  the interpretation of 'wildcards' insofar as
they must be understood in communications between DNS servers,
i.e. zone transfers and NSEC type records.

A DNS server may effectively support any configuration language
it chooses and support 'macros' that expand according to any
semantics that are useful to the sysadmin. 

So *.example.com is a DNS wildcard.

But a server may implement a configuration language that supports
_ssh._tcp.?.example.com if it chooses to. Or for that matter
matches of the form www?.example.com if it choose to.

A standard definition of such macros might help understanding but
is not necessary for interoperability.

*  - matches only nodes that do NOT exist
?  - matches only nodes that do exist
*? - matches all nodes.
