FYI, If u add a handler through registry xml, which will goes in to user
defined system handler phase (system) which is also executed after "tenant"
phase. In registry, generally such user defined handlers added in a phase
where those will not get hit prior to handlers like MountHandler,
CacheHandler etc.
But still if you want your handler to get hit before mount handler, you
have to register your handler in default system handler phase. That you
have to register your handler programatically in your bundle startup. You
can obtain handler manager via registry service to register a handler.
