Well that's not the case, WebDAV is really not about *what* you can 
upload, but more about what happens on upload...

Let me sum up what Silva should currently be capable of:

* browsing the contents of the server using a WebDAV client
* retrieving contents using a WebDAV client
* creating new folders (MKDIR will create a Silva Folder, not a 
publication, currently)
* moving existing Silva objects
* copying existing Silva objects
* uploading content of an unknown file type, the result will be a Silva 
File object
* uploading images, resulting in Silva Image types being added
* uploading HTML, which should result in creation of a Silva Document
* uploading XML with a .slv extension, this should result in creation of 
a Silva Document
* uploading HTML or Silva XML (.slv) to an existing Silva Document

and all this with checks on security and publication state.

What is not (yet?) supported:

* locking
* versioning control from WebDAV (DeltaV)
* setting and retrieving metadata

and some more advanced features of WebDAV.

Also note that some WebDAV clients have a really nasty way of creating 
files (which involves creating a 'resource' without contents, and later 
uploading the contents, which interacts pretty badly with Zope DAV), 
currently I didn't find a way to work around that, hopefully I can fix 
that later. Creating content with more 'standard' tools like Cadaver 
works just fine, but some clients (notably the Windows and OS-X (iirc) 
desktop clients) won't let you create any non-collection resources.

Hope that helps a bit.

Cheers,

Guido
