Hi Gustav,
$ mk4ht teimlatex sample2e.tex
...
! Undefined control sequence.
l.1616 \CssI get exactly that same error, both with unmodified TL'12 and with the current tex4ht *.4ht files. I expect no one has looked at the TEI output since Eitan died. Certainly I haven't. So this would be a great place for your group to start digging into the code :). Best, Karl
