Wrong.

The empty namespace name is a "default namespace undeclaration" and
therefore can only be used when unprefixed:

[Definition:] If the attribute name matches PrefixedAttName, then the NCName
gives the namespace prefix, used to associate element and attribute names
with the namespace name in the attribute value in the scope of the element
to which the declaration is attached. In such declarations, the namespace
name may not be empty.

[Definition:] If the attribute name matches DefaultAttName, then the
namespace name in the attribute value is that of the default namespace in
the scope of the element to which the declaration is attached. In such a
default declaration, the attribute value may be empty. Default namespaces
and overriding of declarations are discussed in "5. Applying Namespaces to
Elements and Attributes".
