> The simple language can currently only be used for
> - string concats
> - as predicates to check for existence of a given header/property etc.
> - access to system properties, headers, body etc.
> - some simple date/java.text formatting
> But if you use it in Spring DSL in choice etc. then end users would like to 
> do some simple operator matching such as
> {code}
> $in.header.foo = 'bar'
> {code}
> Currently you have to use eg EL, mvel, ognl or other scripting language for 
> that.
> But maybe we could add a very simple operator syntax for just the basic 
> stuff. eg we have in the ExpressionBuilder/BinaryPredicates with isEqual, 
> isNotEqual etc.
