I read the draft and tried to find the reason by searching the
archive. Why are startpoint and endpoint (SP and EP) missing?
The options are even mentioned in Appendx B. Adding these
options would e.g. allow to implement distributed downloads where
parts of the same file can be downloaded from different mirror-
servers at the same time checking the hash of each part.

In case you want to add another entry to Appendix B:
Lobster IntegrationServer (supports XCRC, XSHA1, XMD5; all with
SP and EP).
