Depends on the stanza.

For message, the RFC says default to "normal".

For presence, there is no default, so probably if the 'type' is an
unknown value it is better to return an error (solves the presence
leak). IMHO the error should be <bad-request/>.

For IQ, only the defined values make sense (structured interaction) so 
here again I think it is proper to return a <bad-request/> error.

I'll clarify this in rfc3920bis / rfc3921bis.
