The distinction can be clarified a bit by pointing out that:
QCLASS=* is ALL but QTYPE=* is ANY
and that really much of this confusion can be categorized as the ugly
remnants of an ingrained UI-overload condition, where a single wildcard
mask ("*") is commonly used to represent two different actual queries.
Nobody should call it qtype=*, because its not, and because it perpetuates
the confusion.
