Hi Geoff (or any other XML experts),

I have a client and a server on a single machine which do the reporting
I describe
below. 
But if I want to distribute them to different machines they must speak
WebDAV-XML
with each other. That's a language I'm not fluent yet :-).
So perhaps somebody could give XML lessons to my client and server ?
I would like to get a XML example for that before I implement something
wrong.
BTW, wouldn't it be nice to add a scenario section to our faq-o-matic
FAQ ?
I would add the examples there if I get them.

My starting point would be the baseline-controlled collection.
At first I guess I must find e.g
 bcc.version-controlled-configuration.checked-in.baseline-collection
Then I suppose I must do a PROPFIND on the baseline-collection (Forget
subbaselines
for the moment. I think I can figure that out by myself if I know the
other stuff)
As a result the client would like to be able to extract the following
information:
	1{<path relative to bcc> <version url>} 
I hope I don't need too many requests for that.

Could you give me an example beginning with a root collection perhaps
with
a checked-out version-controlled-configuration with two VCRs. One
checked-in,
one checked-out. And again my client would like to be able to learn
something: 
	{<path relative to bcc> <version url> (checked-out | checked-in)}

And then I want my client to do a 'compare-baseline-with-configuration'
to tell
me what I already changed in my workspace in comparison to a baseline.
But that's
my problem to solve. Even if it would be nice to delegate this to a
'compare-baseline-with-configuration-report' :-)

> By VCC, did you mean VCCn or VCCl?
By VCC I meant VCCn. I don't care about VCCls at the moment:-) I hope I
will
remember next time to avoid writing VCC.


Then a remark to the label header discussion. Once upon at time I
thought labels
(Kowing RCS, ClearCase, ...) were a simple concept.
But in an HTTP header together with Depth they seem to make problems. By
this I mean
that they loose the property to be easily understood.
So perhaps it would be better to drop the Label header for PROPFIND and
require
an UPDATE(label) + PROPFIND instead ?

I think we must be careful to introduce functionality that's difficult
to grok.
So perhaps it's better to drop a clever shortcut when it's not obvious
what it
will do. But perhaps it's just a matter of learning the DeltaV mindset.

Cheers, Edgar
