DAVENPORT: Headers and footers in print stylesheet

[Richard Jones <richard@deep-thought.org>]

I'm sure there is something very obvious I'm missing here but how do I 
go about getting my docbook output to produce headers and footers? I
assume the stylesheets grab something from the docbook markup to
output as headers/footers. Looking at the .dsl's there does appear
to be something like this going on, I just can't figure out how to
turn it on.  As an aside is it possible to have a graphic in the
footers (i.e. something like a company or product logo).

Thanks,
	Richard.
