What perhaps fixes this problem is defining my own section command like this:



According to the wiki
(http://wiki.contextgarden.net/Command/setupbackgrounds) that should work,
but Context doesn't seem to understand the syntax and prints the part:
"[background=color,backgroundcolor=gray]" before the section title.

What did I do wrong?
