Sorry, not good enough.  When someone sends me a pile of what's alleged 
to be XML

(a) I can use lots of impartial 3rd-party software to find out whether 
it really is or not, and
(b) That software runs pretty fast, and
(c) It never breaks non-ASCII characters.

I've actually had consistently nasty experiences with (alleged) ASN.1. 
Is there actually a widely-available utility out there that I can 
download from somewhere that will reliably and robustly read BER-encoded 
ASN.1?  Google dosn't find much.

There's some stuff from IBM Developerworks (you have to download a 
mountain of other Java to get it to work, sigh).  If this silently 
refuses to unpack the BER should I feel confident in throwing the BER 
back in the data provider's face?  -Tim
