XProc does (as I understand - I've only recently started using
Calabash) at least already provide some means to process xsl:message
output - as stated in the spec at http://www.w3.org/TR/xproc/:
it is common for all xsl:message output from the XSLT component to
appear on the error output port
- it's unclear from this whether xsl:message output is somehow
converted to well-formed XML by the XProc processor (I'm guessing it
should be), and perhaps XProc 2 should address this - but given my
unfamiliarity with XProc I'm not quite ready to pursue this at the
moment.
However, instead of an XProc solution, I was rather hoping that with
streaming XSLT there would be a neat way to bind an XSLT 3.0 template
to the message stream of one or more transforms. My standard XSLT
test-harness exploits multi-threaded processing - providing a
real-time count of errors and messages but results are only merged
once all tests are complete. I feel it would be much more elegant,
portable and maintainable if more of this test-harness could be coded
in XSLT instead of the current mix of C# and Java.
Thanks

Dear list,
With XSLT 1.0 and 2.0 there is (so far as I know) no specified way of
assigning a 'native' XSLT listener to the message output from
xsl:message instructions or to the error output.
This might be an interesting use case for XProc 2. Feel free to submit
it to the XProc Working Group (let me know if you need help negotiating
the W3C Maze to do that).
