Hello Mike and Martin,

Thank you for confirming this. It's the escaping even more than the
indentation that worries me.

In my experience, there is no set of whitespace rules that everyone will
agree is ideal or even very nice. But it is also not so difficult to do
better than the brick.

I will definitely look at that XSLT (in the spec). I could perhaps use
Javascript .stringify except I would like to inject the raw JSON for
display into the page, which is so easy to do in SaxonJS. Indeed, in this
case I am afraid the 'right way' is to do it in XSLT. A variant could
produce markup for syntax coloring.

Thanks, Wendell
