Bug in MathML test suite?

I think there is an error in test

more precisely in the line:

   <mo lspace='2' rspace='1'>+</mo>

A value without any unit for attributes lspace or rspace seems
to be wrong.  The definition of these attributes (section of the MathML 2.0 Rec.) implies that units are mandatory.
There is no brackets around h-unit in the definition, and according
to section, only brackets make unit optional.

If my reasoning is right, the last sentence in the Description of
the test is wrong too ("Units should be ems by default"), as there is
no default units for lspace or rspace.
