The calendar-proxy-write and calendar-proxy-read "sub-principal" resources 
are in effect "groups". So If user09 wants to make user10 a read-write 
proxy, all they need to do is add user10 to the DAV:group-member-set WebDAV 
property of the user09 calendar-proxy-write resource. So a simple PROPPATCH:

PROPPATCH /principals/users/user09/calendar-proxy-write HTTP/1.1
Host: localhost
...

<?xml version="1.0" encoding="utf-8" ?>
<D:propertyupdate xmlns:D="DAV:">
<D:set>
<D:prop>
<D:group-member-set><D:href>/principals/users/user10</D:href></D:group-member-set>
</D:prop>
</D:set>
</D:propertyupdate>

Note that you have to re-write the DAV:group-member-set each time, so you 
need to get the existing list first and make changes to that as a whole, 
then update the entire list via the PROPPATCH.

And yes, our server does support adding group principals into the 
DAV:group-member-set property and the server takes care of automatically 
"expanding" that and effectively making all members of that group a proxy 
for the relevant user.
