Different styling for formal objects

[Zbyszek Cybulski <z.cybulski@gmail.com>]

Hi, 

As stated in Bob's book, the title of figure, table, example, equation
and procedure objects share the same print styling. The position of
titles can be customized (before or after) but I can't find, how to
customize the styling for different objects.
Say, I want to have the procedure or example title bigger than the
base font and bold, while the figure title (can I say, caption?)
smaller than the base font.
Is it possible and what do I do to achieve this? I want PDF as output
(Docbook 4.4 + Xalan + XEP to process my source files).
I am still too fresh with XSL, XSLT and Docbook, so my problem can be
just lack of reading. If so, I apologize.

Tks,
Zbyszek
