Phil,
I'm not 100% on what you mean by policies. Policies covering BCM are usually included within an organization's security policies. There is some association with ISO 17799/27002 in this respect, as section 5 of this standard specifically covers such policies. You might wish to take a look at that.
Bear in mind too that 25999 is just one of a number of current initiatives in the BCM area. It is probably worth waiting for things to settle before thinking about categorization on Elsmar.
One final point: contrary to some of the information in circulation out there, part 2 of this standard will not in fact be published on 25th September, as origianlly planned. The most likely date is now sometime in November.
Hope this helps.
