Florian is correct: it is best to do all logic like this in an action as opposed to in the
Velocity code.  You will have a lot more flexibility in the action, plus you can reuse your
code that way.

No, there is nothing right now to have common properties.  I would rather not put them in 
pages.xml though because that file is only used when using the XMLPageManager.  Or at least
I would first like to come up with a way to do it using the default page manager.  I'll think
about it for a bit and see where it would best fit.
