Using foot variable to help control page footer?

Hello,

I am trying to add a customer footer to every page (a simple
copyright).  After reading [1] from the FAQ, it said to using the
variable <xsl:variable name="foot"/>.  I found the template
<xsl:template match="*" mode="running.foot.mode"> inside pagesetup.xsl,
but no mention of the variable "foot".

I am using the RedHat 9 RPMs, including:

docbook-style-xsl-1.58.1-2
xmlto-0.0.12-3

Am I missing something, or is the FAQ referring to either an old or too
new version of pagesetup.xsl?

Any tips on getting a custom footer working w/ the RH9 xmlto chain would
be greatly appreciated.

Thanks very much!
Seth
