just a small correction. We've changed the syntax to support both 
variables and xpath statements in AVT syntax. So your above statement 
must be written:


additionally you can access an instance node via xpath like this

This will result in

action="http://yourhost/someUrl" provides that the instance node 'bar' 
has the value 'someUrl'.

Note: this syntax change occurred after the last release of Chiba Web 
(2.0.0rc1) and is currently only available in our CVS HEAD.
