------------------------------------
Rahul,
I tried to find a compact solution and added patches for 3 files.

> Key: SCXML-76
> URL: https://issues.apache.org/jira/browse/SCXML-76
> Project: Commons SCXML
> Issue Type: Bug

> The SCXMLSerializer does not escape expression strings. With an EcmaScript evaluator the following may occur:
> original document:
> <transition event="foo" cond="i < 3" target="bar">
> the serialized document will be:
> <transition event="foo" cond="i < 3" target="bar">
> which is ill-formed XML. The serializer would need to escape the condition string. This applies to all places where expressions may occur.
> Apache commons-lang has a StringEscapeUtil.escapeXML(String data) function which would solve the problem (I don't know if it would help for all cases).
> http://svn.apache.org/viewvc/commons/proper/lang/trunk/src/java/org/apache/commons/lang/StringEscapeUtils.java?view=markup
> But using this would add another dependency to commons-scxml.
