Thanks, that does the trick.

However, now I get an error when I try to return a key-value setting via xmlmap, see below. Any hints why this does not work

\xmlmapvalue{colgroupalign}{dir: rtl}{align=righttoleft}
\xmlmapvalue{colgroupalign}{dir: ltr}{align=lefttoright}

as opposed to:

\xmlmapvalue{colgroupalignvar}{dir: rtl}{righttoleft}
\xmlmapvalue{colgroupalignvar}{dir: ltr}{lefttoright}

?

Best,
Denis
