this is a yacc parser.  there is no way to distinguish error severities
between an extra "}" (which would make the rest of the file unreadable)
and "type mister" (misspelled keyword).  there are other things which
can occur after parsing, like ACL names not matching, that could be
treated as warnings rather than errors, but anything which caused a zone
to not load should in my opinion be fatal to the entire configuration.

yes, which is why i made my other proposal...

...and now i just need to write it up and put it on the work queue.
