Syntax for object name pattern

Thursday 09 March 2006 7:10:49 am

What are the possibilities here?

I have seen:
<title> (taking the value of an attribute)
and
<short_title|title> (taking the value of an attribute if it exists, or the value of another attribute as a fallback value)

I also tried:
name (literal name)

But I would like to be able to do this:
<short_title|'default'>
Use the value of attribute 'short_title' if it exists, or a hardcoded default name otherwise.

Is this possible, and how?
What other object name patterns can I use?
