I am trying to use EMF JET to traverse an EMF model. I am able to access the
members of the model, but I need the equivalent of the EMF Switch utility
class to distinguish instances of subclasses. I would like to use the
built-in XPath functions, if possible.

Concrete case: I have a Script metaclass, which has an eReference to a Steps
Metaclass, that are of different subtypes. I have to produce different
output for each case. How can I write this in EMF JET?

What is the test predicate of the conditional?

<c:when test="value">
content to process if tag condition is satisfied
</c:when>
