Using the jsontoxml policy, How can I append a namespace to object root element?

[NikhilAnand_whp]

I am going to get input request with JSON format like below

{
  "Name":"Joe",
  "customerId":"1234",
  "Age":"12"
}

whereas at Apigee side I need to convert this request into XML format like below

<ser:root xmlns:ser="http://test.com">
  <Name>Joe</Name>
  <customerId>1234</customerId>
  <Age>12</Age>
</ser:root>

There is no extra conversion required; the only requirement is the root element namespace. I want to achieve this without javascript or xslt policy. Please assist. The JSON_XML policy doesn't help in with the root namespace. Attribute names are dynamic, meaning another request I can get country or address. So I can't extract individual attributes.

@dchiesa1 - is this possible without the javascript or xslt policy ?

No, not possible as far as I know. The jsontoxml policy does have an ObjectRootElementName configuration element, which allows you to specify  the "root" as your desired root element name.  But it does not have the corresponding ObjectRootElementNamespace . That would be a good extension. In fcat it's so obvious that I 'm surprised I haven't heard this request previously, and I'm surprised the builtin policy doesn't already do this. 

The way I would do it is, either pre-process with JS or post-process with XSLT, as you implied. 

Good luck.
