org.apache.synapse.mediators.template.TemplateMediator
This mediator is responsible for handling function templates for synapse. This will parse parameters passed from an mediator and will be made available to sequences defined within this template. parameters will be accessible through synapse 'function stack'. Users should access these through an xpath extension var or function , defined under function scope ie:- $func:p1 or get-property('func','p2')
