Related bonus questions, try to err towards gratuitous redundancy.

   * The ''Evaluator'' is a component with the capability of parsing and evaluating expressions.
It is the "expression language engine".
  
  Commons SCXML currently provide implementations for [http://jakarta.apache.org/commons/sandbox/scxml/apidocs/org/apache/commons/scxml/env/jexl/package-summary.html
JEXL] and [http://jakarta.apache.org/commons/sandbox/scxml/apidocs/org/apache/commons/scxml/env/jsp/package-summary.html
JSP 2.0 EL].

  A few examples are available as part of the [http://svn.apache.org/repos/asf/jakarta/commons/sandbox/scxml/trunk/src/test/java/org/apache/commons/scxml/
Commons SCXML test suite] (look in env packages as well). Enjoy, and feedback is always welcome.
  
+ ==== Can I use more than one expression language in the same SCXML document? ====
+ 
+ No, the expressions throughout the document must be homogeneous. This also applies to any
external documents that may be refered by this document, for example via {{{src}}} attributes,
like so:
+ 
+ {{{
+ <state id="foo" src="foo.xml">
+   <!-- Something, possibly very interesting, here -->
+ </state>
+ }}}
+ 
+ Here, {{{foo.xml}}} must use the same expression language as the document above that hosts
the state {{{foo}}}.
+ 
  ==== How do I enable / control the logging within the Commons SCXML package? ====
  
  Commons SCXML uses Commons Logging. See the [http://jakarta.apache.org/commons/logging/
Commons Logging Website] for more details.
