I certainly support having a list of REL and REV values, and I also support
people experimenting with new ones, but I must admit that I question the
value of sticking a "X-" on the beginning of an experimental value. I take
it as a given that software will not fail on encountering a value that it
doesn't support, and if you stick on "X-" on the beginning of experimental
things, it just means you need to change your software once it does get
standardized (Because the act of standardization changes existing practice).
