I have extensive experience with ASN.1. Out of the fact that I am  
good friends with some of the people behind it, and also because  
until the end of the month by chairship of the EXI WG requires of me  
total neutrality, I shan't describe this experience :)

But what I can say is that ASN.1 simply doesn't fly IMHO as a binary  
XML format because a) it requires a schema and b) it doesn't handle  
deviance from schemata at all. Both these facts make it inapplicable  
to at the very conservative least 80% of real world XML usage. It  
also has a few other issues depending on the encoding rules you use,  
e.g. BER is not sufficiently compact, but PER isn't streamable.
