Do you have an example of this? I'm curious what character you could have in JSON that you couldn't represent in XML using the '&#' syntax.
Edit: To answer my own question, backspace is an example of such a character.  is not valid XML.

This. I'm not claiming it is a good idea... But, DataPower is a highly optimized data processing network appliance for XML. It provides transform speeds with minimal latency, etc. So, to extend its capabilities to a new popular data format (JSON), they transform JSON to XML.
It may be somewhat problematic that it doesn't actually support all JSON, because the characters that are permitted (even with escapes) in XML 1.0 text do not include all characters that can appear in JSON values, so if you use it on legal JSON that isn't constrained to be XML 1.0 compatible, it will do something wrong (the docs aren't clear on whether it will fail or just drop the offending characters), so the only place that it seems safe to use is in a constrained internal environment where you control "JSON" to mean "JSON using XML-1.0-safe characters".
