This particular header name won't work this way because it has a '-' and
the parser intterprets it as as:
 @msg.Referred  - By.nameaddr.uri

(that's why you get the error about missing (), the parser thinks you
wanted to call a function named By.nameaddr.uri())

So if a select parameter contains a special characted (or better
anything besides [a-zA-Z0-9_]), use ["..."] (we should document it
somewhere).
