When to prefer JSON over XML?

Favor XML over JSON when any of these is true:

	You need message validation

	You're using XSLT

	Your messages include a lot of marked-up text

	You need to interoperate with environments that don't support JSON

Favor JSON over XML when all of these are true:

	Messages don't need to be validated, or validating their deserialization is simple

	You're not transforming messages, or transforming their deserialization is simple

	Your messages are mostly data, not marked-up text

	The messaging endpoints have good JSON tools
