True. Our approach does not require a schema, but enables schema-based validation.

Regarding Yang vs ASN.1, there are several diskussion threads not least in the Yang diskussion forums on why a new language would be better for NETCONF than using e.g. ASN.1. I'm sure Martin Björklund* could give a dissertation on the topic, since he is the main author of the Yang RFC. Whether he wants to is another matter. :)

Personally, I really prefer Yang over ASN.1.
