Hi John,
I use the free version of Saxon 96 (but also have Oxygen, which may have 
some other processor). Will your citation work with that? (I am very 
much a novice with XSLT).
Went to your citation and was pleased to see the ASN1 reference -- I 
developed several C++/ASN1/BER applications for Z30.50 back in the day 
(I am 77 now). I will look over the stuff and see if I can do anything 
with it.
Thanks,
Mark
