Agreed. Suggestions for how? I find only inelegant solutions -- like
keeping a list of known params -- and it seems like there /should/ be an
elegant solution to this problem. :-)

Sorry! I /said/ I was feeling dense... :-)

«We can hardly do...» What, exactly? Suggest escaping characters in the
URI? Why not? What /should/ we do then? There is no way we can tell the
difference between «;» and «;», if you see my dilemma? :-)

My German-fu is a little weak, but I think I got the gist of it. For the
hapless user in question: I apologize most humbly for the failure and will
endeavour mightily to correct my erring ways. Just as soon as I figure out
what they are and how to fix it. :-)

IOW, it's clear the Validator needs to be «fixed» in some sense or way. I'm
just not quite up to the point, as yet, where I grok the specifics of the
«How» and the «Why» (much less the «When»; as Gerald is AWOL the next
couple of weeks).
