Yes.
The point as I understand it was that 
processing-instruction(), comment() (and, I can add, text())
*look* like functions.
Just today, for some silly reason, I was horsing around 
with "text-node()" and reverted to the spec
to find out the correct syntax is "text()". 
In Michael Kay's excellent book, a subentry "XPath syntax" under the index
entries
for "processing instruction", "comment" and "text node" pointing to p.372f
would have done the trick within seconds.
