What I said was not what I meant.  What I meant by default was the default 
restrictive case, otherwise the limits are ignored.  I am gathering from all 
this discussion that all that is really needed is a warning when the limit is 
exceeded and there is no need for an error.

I will wait for any other comments, before continuing.
