copyright notice on last page

I need to adhere to a document standard that demands a copyright
notice on the _last_ page of each document. 

Any ideas who to do this? I use fop to generate pdf output.

My first thought was to misuse <colophon>, but all the information is
also included in <bookinfo> and I don't want to havee the information
twice in the document.

I'm no xsl:fo expert. Thus I have a vague idea that I need a special
pagemaster and corresponding stylesheet templates. Is that the way to
go? If so, I'd appreciate any pointers which templates I need to
customize and how.

Cheers
Martin
