When the WebDAV writelocking project was in its early stages, some 
debate went to whether the locking mechanism should be exposed to a 
higher level, and what that mechanism would be.  Ultimately, 
however, it was decided that WebDAV writelocking would be kept 
entirely within the WebDAV system.  It's not recommended that you 
try to use these outside of that, primarily due to the importance 
of the 'locktoken' objects, which you need to understand in order 
to use wl_setLock() and other methods.
