Bug in Daffodil? "textBidi not allowed to appear on xs:element"

[Costello, Roger L.]

Hi Folks,

I placed dfdl:textBidi="no" on an element declaration. Daffodil says that's not 
legal:

Attribute 'dfdl:textBidi' is not allowed to appear in element 'xs:element'.

The DFDL specification says this:

Annotation: dfdl:element, dfdl:simpleType (representation text)

Which is right - the DFDL specification or Daffodil?
