It's probably using XSLT under the hood, with a stylesheet that's
usable e.g. with Saxon. You do pay the penalty of Java runtime startup,
though.

Note also that XSLT 3 includes a standard function to produce JSON; see
https://www.w3.org/TR/xpath-functions-31/#json-to-xml-mapping

So you could just use xml-to-json() in XSLT. You may need Saxon EE for
that, i'm not sure offhand.

Of course, you could also just send XML to the Web client; what you are
doing by using a complex transformation into JSON is moving the
complexity from one developer to another. You could also generate HTML
on the server, whic might make it easier to meet 508/WCAG requirements
:)
