[xwiki-devs] Macros and 1.0 2.0 xwiki syntax

I have a java macro which I've written that I'd like to reference from a panel. Is there a way to use xwiki 2.0 syntax in a panel so I can invoke my macro? It would appear that panels utilize 1.0 syntax? As a workaround I added yet another 2.0 page with just the macro invocation and then included that page in the panel. It seems like a catch22 if I create a component macro I can only use it in 2.0 and if I create a radeox macro I can only use it in 1.0. How does one write a macro that can be accessable from 1.0 or 2.0 as well as from a panel? Or, will the 1.0 be jettisoned entirely at some point ? Thanks, Glenn
