/**
* Updates one ore more webdav properties on a principal.

* a propertyname, such as {DAV:}displayname.
*
* Each value is the actual value to be updated. If a value is null, it
* must be deleted.
*
* This method should be atomic. It must either completely succeed, or
* completely fail. Success and failure can simply be returned as 'true' or
* 'false'.
*
* It is also possible to return detailed failure information. In that case
* an array such as this should be returned:
*
* array(
* 200 => array(
* '{DAV:}prop1' => null,
* ),
* 201 => array(
* '{DAV:}prop2' => null,

* '{DAV:}prop3' => null,
* ),
* 424 => array(
* '{DAV:}prop4' => null,
* ),
* );
*
* In this previous example prop1 was successfully updated or deleted, and
* prop2 was succesfully created.
*
* prop3 failed to update due to '403 Forbidden' and because of this prop4
* also could not be updated with '424 Failed dependency'.
*
* This last example was actually incorrect. While 200 and 201 could appear
* in 1 response, if there's any error (403) the other properties should
* always fail with 423 (failed dependency).
*
* But anyway, if you don't want to scratch your head over this, just
* return true or false.
