No, it removes all current representations.  It is the equivalent
of rm in the Unix filesystem -- it removes the current association
between the name and whatever that name formerly mapped to.
In essence, it deletes the name from the directory record and
may (or may not) have some impact on the storage system as a
result.  It does not prevent the next request from recreating the
same name via PUT, and hence does not delete the resource because
the identifier is still valid.
