RE: embed XML island in stylesheet?

Dan,
Since you prefer to talk to DC direct and give me no credit for my maybe
slightly flippant (absolutely correct) answer I won't give you the
obvious (and easiest) solution. You'll have to wait another 6 hours for
the great oracle. 
Key huh! You are at the end of a long dark passage. To the left is the
current stylesheet. To the right is a small piece of stylesheet. A
little xpath is singing.
Take Rod!
Nothing happens.
Plugh!
Nothing happens.
Xyzzy
Nothing happens.
There is a cage here!

Ciao Chris
