They are testing different cases - you really need to read the XML 
Namespaces spec very carefully and implement that if your XML parser 
doesn't do it for you.  propfind_invalid2/propnulls are testing:

xmlns="DAV:" -> set default namespace to DAV:
xmlns=""     -> reset to no default namespace
xmlns:bar="" -> invalid XML namespace declaration, parse error
