Tim,
The above code is only related to the XHTML render pipeline... stuff that
goes through Lift's view mechanism. It would be a Bad Thing (tm) to set
JSON as the return type in this case as the result is going to be XHTML.
The reason we've got this particular bit of code is to deal with IE 6/7 (no
XHTML support and barfs on "application/xhtml+xml" headers but modern
browsers (FF, Safari, etc.) require the content type to properly render the
page (not apply some alternative of HTML tag soup to the page.)
More broadly, the content-type must match what is actually being rendered.
In the case of APIs, you will have alternative dispatches to functions that
are going to render the result *and* set the content-type headers
appropriately.
I've been noodling on some sort of meta-representation of stuff that could
be auto-converted into XML or JSON, but the noodling hasn't gone too far.
Thanks,
David
