Something seems to have gone wrong with the <param-type> defintion on page 212.

But the rule for <formal-parameter-list> on page 211 now suggests that  "..." can be used in the 
middle of the other declarations, which is not true.

	formal-parameter-list = "(" [ parameter-declaration { ";" parameter-declaration } ] [ "..." ] ")" .

I didn't see a rule for <variable-reference> yet in the Language Reference.
