Section 9.1.1 Internal Properties and Methods of the E4X specifications says
about the [[Parent]] property:
  "The value of the [[Parent]] property must be either an XML object or null."
The method parent of an XML object maps directly to that internal property as
the specifications says:
  "When the parent method is called on an XML object x, the following step is taken:
!!!1. Return x.[[Parent]]"
thus I think if an XML object has no parent then Rhino should return null when
calling object.parent().
Rhino (Rhino 1.6 release 1 2004 11 30) however returns undefined which is a bug.

Test case to be run in the Rhino shell:

var xhtml = <html xmlns="http://www.w3.org/1999/xhtml"></html>;
'xhtml.parent() === null: ' + (xhtml.parent() === null) + '\r\n' +
'xhtml.parent() === undefined: ' + (xhtml.parent() === undefined)

yields 

xhtml.parent() === null: false
xhtml.parent() === undefined: true

but should yield

xhtml.parent() === null: true
xhtml.parent() === undefined: false
