Andreas Veithen commented on SYNAPSE-235:
-----------------------------------------

I know that you already started to modify the code, but I was wondering if it 
would not have been more elegant and perhaps even simpler to use XPath 
variables to do this. For example:

expression="$body/getQuote/request"

I'm not 100% sure that this is feasible, but I know that in XPath a variable 
can be a node set (meaning that it in particular it can reference a single 
node). Also, Jaxen supports this (see 
http://jaxen.codehaus.org/apidocs/org/jaxen/VariableContext.html).

> Default could be envelope (i.e. what we have now - for backward
