I strongly encourage you to try all your ideas and to look at the generated
java file...
It's the best way to see what really happens.
Anyway, here are my personal feelings (I work with C1)... But I'm not a
cocoon guru yet :) (the code will tell you the all truth!)

creates a text node containing "theInstance", not what you want

good

session variables contain Object... look at the code to see what really
happens

yes, it should work, but I don't see why you put theInstance inside
xsp:expr...
Everything in xsp:logic is treated as code, except when you use xsp:content

good idea, I do it myself :)
