[Mono-dev] XmlDocument.CreateElement

[Atsushi Eno]

Hi,

Yes, by design. Note that since you didn't specify namespace URI
for any of the elements you created, their namespaces are empty.
Without namespace URI, elements and attributes are not allowed to
have prefixes by "Namespaces in XML" specification.

XmlDocument does not support namespace-less documents unlike
XmlTextReader (which has Namespaces property).

(The same behavior as .NET.)
