Right.  Additionally, xsi:type can specify a complex type which in turn 
gives an attribute the xs:id type.  Perhaps that's what's intended by the 
original quote?  I believe it is possible in principle.  Indeed, this line 
of reasoning somewhat bolsters the claim that the existing wording is 
unnecessarily vague and should be clarified.

xsi:type can give types to elements which can be typed as instances of
xs:ID or xs:IDREF. There is language in the REC discouraging people from
doing this since it is not compatible with DTD functionality.
