DateTime
- Microsoft totally ignores the Timezone which is send by CreationDate
- the SPEC was changed so it is allowed only to send UTC
- Markus developed a DateFormatter which converts the received and sent DateTime to the right format

Namespaces
- Microsoft didn't understand the default namespace
- if you have a propfind MS needs a prefix for xml-tags
- solution
- add a property to the jax-b context so it is forced to generate a prefix
- attention 
- it seems that jaxb sorts the used namespaces internally
- so you shouldn't add a namespace to that property otherwise it could be, that the DAV namespace is default again and your new property has a prefix

Root and OPTIONS
- for using webdav MS needs that your root source is webdav enabled
- solution
- just deploy a resource with PATH("/") and an OPTIONS-Method which returns a response with DAV-Header

foo is Back again
- If you trace your communication while office tries to open an office document you see funnny things sometimes :)
- Office tries to find a folder called "foo" -> a forgotten source code line or just a test -> what happens if this folder would be there? :)

ffnen eines MS Dokuments von einem Netzwerk-Laufwerk:
- Office 2003/2007 hngt sich auf bei dem Versuch eine MS Office-Datei von einem Netzlaufwerk zu ffnen.
- es scheint so, als wrde er dann auf ein Mal auf Web-Folder umswitchen und hngt sich auf
- laut WireShark kommt die GET-Anfrage aber sauber durch

Root-Resource kann nicht als WebDAV-Folder eingebunden werden:
- net use X: http://localhost/ geht nicht
- net use X: http://localhost:80/ geht nicht
