I'm not sure how you can say that. I just tried with comments and PIs in 
Apache/moddav, and they aren't preserved. Do you have any data 
supporting your claim?

Well, because commments are just that -- comments?

This I agree with, but it seems that we don't have the necessary 
supporting data.

I don't want to be lax. We should either document what we have today (if 
we want to advance RFC2518), or document what we tjink would be good 
(staying at proposed). Throwing in things like PIs, but keeping out 
*essential* things like prefixes doesn't make any sense to me, though.
