I wasn't aware of the openejb plugin.  Where is it exactly? How much do 
the tags vary from the regular "ejb" xdoc plugin?

Thats the million dollar question :)  I'm still trying to get familar 
with the geronimo deployment plans, but I would think that not 
everything would make sense or be applicable to have tags for.  Most 
tags generate either xml or additional source.  Could there be any 
scenarios for codegen? (besides openejb tags).  Also it would only make 
sense to provide tags for elements that can be applied to the scope of a 
given class, if that makes sense.  And I think the gbeanplugin would be 
a good example of that.  Also it would good to focus at first on 
geronimo specific non-j2ee tags, and a GBeanPlugin falls into that 
category as well.

The other thing to consider for the future is JSR-175 type annotations, 
and wether we want to exploit its "reflection" support in the server 
during runtime.
