Is there a way to generate XML from the configuration/programming used by the Rails AciveModelSerializer gem? AMS seems to only generate customized JSON. XML comes out in a default format.
I've seen references to AciveModelSerialization and that it supports JSON and XML, but the configuration, while similar, is different. What is the story with the difference between them? Is one going away? How do they compare in real use (other than format capability)?
