Draft -17 with three changes

I've submitted a new draft based on comments on -16.  XML and text  
versions at http://ietf.osafoundation.org/xythoswfs/webui/webdav/ 
rfc2518bis until the version submitted to the Internet-Drafts  
repository goes up.

Changes section for this version:

G.12.  Changes in -17

    Change reference for PROPFIND MultiStatus response format from
    section 15 to section 9.2.1

    Add another "except" clause to statement requiring pre/postcondition
    codes to appear in 'error'

    Remove requirement to use TLS -- back to requiring channel to be
    secure.
