Hm... Money conversion can be a complex business operation depending on
external environment.

What about EJB objects?
A DOM object would be also useful.
Speaking frankly, I've already seen something like this we are discussing in
WebLogic Process Integrator (it's a Workflow Engine). You can define your
workflow process using a GUI (it looks like a flow chart diagram) and among
the other types you could define workflow variables of the following types:
Object, EJBObject, XML.
Also, this is related more to other thread about XML-based selectors: in
WLPI you could define your selection logic using built-in functions and you
could combine XML-based selection with other types, e.g.:
<if test="XPath($userInput, '/confirmation/response')='yes' and
compareDate($startDate, $endDate)=0'" >...</if>
where $userInput is type of 'XML' (internally it could be a DOM object) and
$startDate, $endDate are of 'java.util.Date'.
