That's always been the convention, but there has been some noise about deprecating the use of the X- prefex in general (see http://tools.ietf.org/html//draft-saintandre-xdash-03).
For SIP, I believe the convention was never codified into any standard, and it just came along for the ride with the other RFCS that it "inherited" from (such as HTTP). So much as I like to rag on Cisco for non-standard SIP implementations, this is not one of them.
