	// The propfind_invalid2 litmus test case expects an empty namespace prefix
	// declaration to be an error. The FAQ in the webdav litmus test says:
	//
	// "What does the "propfind_invalid2" test check for?...
	//
	// If a request was sent with an XML body which included an empty namespace
	// prefix declaration (xmlns:ns1=""), then the server must reject that with
	// a "400 Bad Request" response, as it is invalid according to the XML
	// Namespace specification."
	//
	// On the other hand, the Go standard library's encoding/xml package
	// accepts an empty xmlns namespace, as per the discussion at
	// https://github.com/golang/go/issues/8068
	//
	// Empty namespaces seem disallowed in the second (2006) edition of the XML
	// standard, but allowed in a later edition. The grammar differs between
	// http://www.w3.org/TR/2006/REC-xml-names-20060816/#ns-decl and
	// http://www.w3.org/TR/REC-xml-names/#dt-prefix
	//
	// Thus, we assume that the propfind_invalid2 test is obsolete, and
	// hard-code the 400 Bad Request response that the test expects.
