Yeah, I did that, and it works for me (patch attached).
Tested in Opera and Firefox in Linux, both with and without data-uri.
Probably this can be done with less copy&paste, without tying it to
xhtml11's variant of imageblock, but I didn't know asciidoc conf files
good enough for this. :(
P.S. I probably hit the bug. In this snippet:
{set2:quot:\"}
{sys:sed "s/<map[^>]*>/<map id={quot}cmapx-{cmapx-id}{quot} …
I had to define {quot} and use it instead of \" because while this works:
{sys:sed "s/<map[^>]*>/<map id=\"cmapx-{cmapx-id} …
this one doesn't work:
{sys:sed "s/<map[^>]*>/<map id=\"cmapx-{cmapx-id}\" …
because it looks like this:
{attribute}\
somehow processed similar to escaping attribute, like this:
\{attribute}
