Actually that won't work, even if I would fix it. The <odb> tag is evaluated on the
server side (mhttpd), where is gets replaced by the actual ODB value. But if you
use JavaScript to generate the <odb> tag dynamically, this only happens on the
client side, so the server has no chance to substitute them. So you have to go with
ODBGet's I'm afraid. Nevertheless, I changed the code such that any ODB tags inside
a JavaScript is not interpreted by mhttpd.
