Having the default namespace declared on an ancestor of the context
element is completely valid in this case, since the soap:Envelope
element is associated with a different namespace. You could see what
happens if you serialise the document using a different library
function or document/node method, however.

Note that according to the specifications, the element name should be
None (null) for this kind of createDocument invocation. See here for
details:
