How to vary point size in an Appendix

["Hamilton, Dick L" <dick.hamilton@hp.com>]

We have a situation where we would like to have
a different base point size for the text in an
appendix than in the chapters of a pdf document.

Using the docbook stylesheets, we can easily change
the base point size for the entire document, but we
are having trouble figuring out the best way to do
it for the appendices only without making some pretty
major changes to the stylesheets, which we'd like to
avoid if at all possible.

Has anyone done this or have any suggestions on
the cleanest way to handle this situation in the
docbook stylesheets?  BTW, it would be fine if we
could define this in relative terms (e.g., the point
size of the appendix is the base +/- X).

Any suggestions would be greatly appreciated.

Thanks,
