It should be in the view, on the link.   I can't see any way that  
trying to put this in pages.xml makes sense.

Note that we already support this to some degree with <f:param  
name="whatever" value="" />.  It's very tedious  to put this on every  
link, especially when you have multiple page parameters, so having an  
easier way to set this on each particular link would be great.
