In description of "5.2.2 Catch", the count attribute

     The occurrence of the event (default is 1). The count allows you
     to handle different occurrences of the same event
     differently. Each <form>, <menu> and form item maintains a
     counter for each event that occurs while it is being visited;
     these counters are reset each time the <menu> or form item's
     <form> is re-entered. The form-level counters are used in the
     selection of an event handler for events thrown in a form-level
     <filled>. Counters are incremented against the full event name
     and every prefix matching event name; for example, occurrence of
     the event "event.foo.1" increments the counters associated with
     handlers for "event.foo.1" plus "event.foo" and "event".

For example

      <catch event="nomatch noinput" count="3">

A sensible interpretation would be that this catch fires after any
combination of "nomatch" or "noinput" (eg. "nomatch,noinput,nomatch").

However, the 5.2.2 description seems to lead to case where "nomatch"
and "noinput" counters are done independently and the example catch
would fire only after there has been at least 3 "noinput" or 3
"nomatch" (a sequence of "nomatch, noinput, nomatch, noinput" would
not fire the catch?

To me it looks like the counters should be kept per active catch
element, and counter incremented once when event specification of the
catch matches? (regardless whether the catch fires or not).
