neon is intended to be compliant with all relevant IETF and W3C standards.
neon is deliberately not compliant with section 23.4.2, and treats property names as a (namespace-URI, name) pair. This is generally considered to be the correct behaviour by the WebDAV WG and is likely to change in a future revision of the spec.
The redirect interface is deliberately not compliant with section 10.3, and will automatically follow redirects for the PROPFIND and OPTIONS methods as well as GET and HEAD. It has been stated that this was the intent of the specification by one of the authors.
