[openbox] Howto highlight menuitems and howto use disabled menuitems in pipemenus ?

[Micha]

In the inbuild menus, there is at least highlighting with bold text.
I've tried to achieve highlighting menuitems in my pipemenus
with ANSI escape sequences and Xml-tags, neither are working.
Is it possible at all, to have the items colored and/or bold displayed ?

And how can I take use of the "disabled" formatting ?
