Why self describing data formats:

I'm not sure what you're getting at.  All XML and S expressions really get 
you is that you know how to skip past something you don't understand. This 
is also true for many (XER, DER, BER) but not all (PER) encodings for 
ASN.1.

Are you saying why publish a schema?
