Rev and XML

[revolution at knowledgeworks.plus.com]

Looking at treeView.rev it looks as though a stack can be traversed and rendered into an XML 
tree.

Using vers. 2.01 this sample stack also seems to be faulty - when loaded it has a default xml 
document that is located in drive "S:\....", clicking on the top right button marked with a 
question mark does not do anything (I was expecting some instructions), and clicking on any 
of the stacks produces an error ("xml err, bad document id").  I even had a look through the
script in the stack but could not find anything that sugggested its purpose.  In fact, it looks
like it was written by another company ("the Attainment Company") and included with Rev without 
proper integration or clarification.  (I'm not moaning - I'm imagining what someone reviewing Rev
2.01 might say!)

These problems aside:  am I right in thinking that a stack can now be converted into XML? 
How far does this conversion go?  (I tested it and the contents of fields are converted, and
button design elements e.g. location are converted, but scripts seem to not be converted.
Could a stack be written as XML and then transformed using XSL into a Rev stack?

Is there some overview explanation of the purpose of XML in relation to Rev?  I've searched
the docs and all I found was references to each specific 'revXML...' command.  A Google
search of this list for "xmltree-view" did not provide anything useful either.
