Hi

Yeah simple does not understand EQ, GE, LT and other operators.

You can use some of the other languages
- ognl
- el
- groovy
- bean (for using POJO)
- xpath if your payload is xml based

See
http://activemq.apache.org/camel/scripting-languages.html
http://activemq.apache.org/camel/ognl.html

Using OGNL it would be
<ognl>request.headers.foo = 'foo1'</ognl>

But I am wondering if we should improve the simple language so it can
be use some simple operators for simple test such as in your use-case.
No need to learn OGNL, Groovy or depend on 3rd part .jars. Just plain Java.

James, any thoughts on this?
