Please help with this WebDAV dialect

Dear all,

We have collected some network traces and have problems to interpret them.
Perhaps you fellow WebDavers can provide us a helping hand:

- Server response 1 adds some extra information after the XML body and does
not add a content length attribute. How should/could one handle this? What
does the "Trailer:" HTTP response attribute mean? (R1)

- Are the DAV: properties within the XML body all valid (e.g. contentclass,
nosubs, id, objectcount, isstructureddocument, uid, visiblecount and many
more) or in what IETF document can they be found? (R1 and R2)

- What does the xml: namespace have as valid properties and how are they
related to DAV? (e.g. xml:v) (R1 and R2)

- Where can we find a definition how to parse tags like <DAV:ishidden
b:dt="boolean">? (R1)

- Is it good behaviour to add so many additional namespaces, which obviously
extend the original DAV protocol definition? (R2)

- Should one mix different namespaces like in <DAV:childcount
b:dt="int">13</DAV:childcount> (R2)
