Copy that. Would it be OK if we alternatively move the extra methods to the camel-datasonnet DatasonnetExpression? I see XPath has support for building expressions from both camel-core-model [BuilderSupport](https://github.com/apache/camel/blob/master/core/camel-core-model/src/main/java/org/apache/camel/builder/BuilderSupport.java#L197) and also from camel-xpath's [XPathBuilder](https://github.com/apache/camel/blob/master/components/camel-xpath/src/main/java/org/apache/camel/language/xpath/XPathBuilder.java#L156). The camel-xpath one actually has optional parameter support, just as we were looking for, as showcased in [this test](https://github.com/apache/camel/blob/master/core/camel-core/src/test/java/org/apache/camel/component/dataset/CustomDataSetTest.java#L34). Here's [an example](https://github.com/apache/camel/blob/master/components/camel-saxon/src/test/java/org/apache/camel/language/xpath/XPathHeaderEnableSaxonJavaDslTest.java#L67) of the camel-xpath one being used in a route instead of the RouteBuilder one. So developers could use the BuilderSupport one if they just want default media types, or the camel-datasonnet one if they want to be explicit in either one or both. Additionally this would allow us to user DataSonnet's formal MediaType objects instead of their String representation. I used the String representation in the BuilderSupport as to not have core-model depend on the DataSonnet Mapper. This would translate into some performance gains as the String will not need to be parsed on each expression evaluation. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
