Using browser XMLSerializer() to produce XML without XHTML entities

Question

I'm using XMLSerializer() to output an in-memory XML document, however it seems to 'entitizing' elements using XHTML standard entities like &nbsp ; . I want to produce an XML document without XHTML entites.

My target DTD does not define these entities, so if a user happens to input a character w/ a corresponding XHTML entity, the serialized document is not well-formed (references an undefined entity like &nsbp;)

Maybe I'm building the DOM tree incorrectly? Or is there another way to avoid XMLSerializer() behaving as if it were XHTMLSerializer()?

worksforme in Firefox 38:

new XMLSerializer().serializeToString(document.createRange()
    .createContextualFragment('<div foo="bar&quot;bar">&nbsp;&uuml;</div>'))

result:

"<div xmlns="http://www.w3.org/1999/xhtml" foo="bar&quot;bar"> ü</div>"

Only standard XML entities and utf-8.
