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? /r$ -- STSM, Senior Security Architect DataPower SOA Appliances http://www.ibm.com/software/integration/datapower/ --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
