Hi Srinath,
Regarding enrich mediator, I think we can get rid of most of the redundant
attributes and support them through xpath only. For instance most of the
operations that you do with enrich can be done using xpath attribute in
both source and target. So, we will fully verify and fix these use cases
while keeping support for existing syntax for backward compatibility.
<!--payload to property -->
<enrich>
<source xpath="//m0:getQuote/m0:request/m0:symbol/text()"
xmlns:m0="http://services.samples"/>
<target xpath="$ctx:PropName"/>
</enrich>
<!-- property to payload -->
<enrich>
<source xpath="$ctx:PropName"
xmlns:m0="http://services.samples"/>
<target xpath="//m0:Foo/"/>
</enrich>
