	I like that one. Shorter than your previous solution. What about the
algorithm? what i like to see is something like:

	How to generate the net list for AS1 at napX:

	If there is a interas-in statment for AS1-AS2 link at napX
		 then
			list all nets in the policy expression (the stuff
			after the 'aacept' keyword)

	If there is no interas-in statment but an as-in statment for AS1-AS2
		policy then
			 list all nets in the policy expression.

	If there is no interas-in statment and no as-in statment
		then
			ERROR!

	If there is an interas-in statment and no as-in statment
		then
                        ERROR! (syntax error)

	etc...

	Remark: this algorithm does not work with the solution you proposed.
