I've had better luck getting data from them that is just not stated 
(as opposed to being outside a stated spec) -- for example, the 
nominal inductance of windings.  I suspect the same might be true if 
someone asked, "What exactly do you mean by 'DC: 30mA?' "  You 
probably wouldn't get hard data or graphs, but they might give you an 
idea of how they arrived at that spec.

In the end, though, the only way to be sure a certain part will work 
in any particular circuit is to build and test it.

Don't forget, you can generally keep DC out of transformer windings 
with shunt coupling (use an RF choke for the DC path, and capacitor 
couple into the transformer winding).  It's an unwanted complexity, 
but some builders may prefer it to winding their own transformers.

Best regards,
