To simplify boostrapping, we're going NIH on scala-xml.
Next step: remove usage in diagram generation, or maybe
move that to a d3 / dot JS client-side solution.

The diff on scaladoc for the core is minimal, using
a textconv à la:

cat "$1" | perl -pe 's/\s+/ /gm' | perl -pe 's/ef26caa/60fce92/g' | \
  tidy -q --sort-attributes alpha --wrap 0 -i -utf8  -ashtml - 2> /dev/null

(shas are part of locally published version)

The html diff in its entirety:
