Question on Sources and Interpretations

[Tara Athan <taraathan@gmail.com>]

There is a point about our metamodel that I am a little confused on.

It's my understanding that some "rule contexts" are themselves legal 
statements. So it seems to me that in such a case the rule context 
itself may have sources, independent of the sources of the legal text it 
is interpreting. I'm not sure if the other properties of legal rules - 
temporal characteristics, authority, jurisdication- would also apply. If 
an interpretation is based on a legally-binding rule of interpretation 
that is then anulled, wouldn't this have effects on the validity of this 
interpretation?

So it seems to me we need to carefully distinguish between properties 
that the rule context *applies* to the text to produced the rule, and 
properties of the rule context itself.
