I don't know that I ever dumped a trace into a document, but it would
do several PROPFIND operations to get where it needed. For example,
one on the public URL to get the VCR, then another to get the VCC,
then another to get the BC. I seem to recall them coming in groups of

In this case, that would compress 3 or more PROPFIND operations into 1
REPORT. But we're going to return a few key URLs in the initial
OPTIONS response, so we've essentially got the count down to 0.

The short answer to this approach is "WebDAV is fine, so we'll keep
that around; DeltaV has failed, so we're going to ignore it." We're
not going to worry about activities, use of CHECKOUT to create working
resources, using a MERGE to create a new version, etc. The resource
model and operations on it are now more aligned with the svn FS

(and by "failed", I mean there has been zero uptake in the software
world that I'm aware of, and most definitely no interoperability)
