I don't know what you mean with "stop". I think
each validator will be
executed, but they will take into account whether
record_type has the
right value.

Anyway, I personally give up :-(

You can try to find out what's happening:

- create your own validator that always raises a
ValidationError (see in
the sources for core.validators to see how)
- add this to your validator list
- do you get a validation message?
  - if not, do something like "raise Blablabla"
which should immediately
result in a backtrace when called. What's happening now?
  - else, change the source of core.validators in Django;
raise
Blablabla in the __call__() method. Do you get the error
message?


You get the picture ...

Hope that helps a little bit.

I created a ticket to add documentation for this module
(#1680)
