Great discussion!

Is it appropriate to share xsltfiddles on here when asking for advice? The
message itself should probably still contains theminimal-but-sufficient
snippets to describe the question, but the xsltfiddle could provide a (still
hopefully minimal) complete testcase for anyone to dive in and have a look.

(Martin, is posting persistent xsltfiddle URLs on here going to increase your
out-of-pocket cost?)
