Subj : Rhino/E4X: what should typeof return for an XMLList object?

When trying to use typeof with the Rhino preview for E4X I get the 
following result:

js> var xmlList = new XMLList("<god>Kibo<\/god><god>Xibo<\/god>");
js> typeof xmlList
xml
js> xmlList instanceof XML
false
js> xmlList instanceof XMLList
true

The specification seems to be ambigious as to what should be returned as 
  section 11.3.2 The typeof Operator says in its text
   When UnaryExpression evaluates to a value of type XMLList, the typeof 
operator returns the string "xmllist".
while the table defining the results says
   Type Result
   XML "xml"
   XMLList "xml"
so Rhino is doing the right thing according to the table but the wrong 
thing according to the text.

Is there an errata for the specification that clears that up?
