I found that enclosing the nested macros in brace insets circumvents both issues (display glitch and latex error). Unfortunately, lyx duly removes the braces when reloading the document, so that this only takes care of the display issue, in practice. See attached. So, the conclusion is that the error is actually due to a limitation of xkeyval. -- Enrico
