A proxy topic is one that is basically the same content as an existing, signed web page.
Is this an PPR:AntiPattern?
Is this different from having two pages about the same thing?
Maybe it is like having a comments sheet attached to something? Except we don't (ahem) always remember to point from the web page to the relevant Wiki entry, which breaks that metaphor...

Consider the page XML. There are plenty of excellent descriptions of XML on the Internet.
