My idea was to encode as much of the current known rules as as we have
the stomach for, and to have a validation flag that you turn on if you
want to check your message against those standards.  But without that
flag the code allows you to set arbitrary parameters and headers.

As you say, an extensible mechanism for the validators is a good idea.
So I take it back that the infrastructure is in place, since extensibility
doesn't exist for that feature yet.
