Thanks for the pointer, this is an interesting extension case. I'm not sure
if the implementation of a compliant WebDAV server *fully* falls into the
scope of JSR-311.
JSR implementations could simply provide mechanisms to extend their
preconditions check logic. In the Restlet API it is already possible, and
I've entered an RFE to consider simplifying this use case even more:
