custom metatdata attributes

hi all,

as we (Leo and I) have talked about custom metadata attribute support
for java lately, I wanted to know whether this should be done inside
avalon, or should be delegated to another (jakarta) project.

if inside avalon, I was wondering what approach towards implementing
them should be taken. (class augmentation, manifest files, ...)

I am curious about your opinons, and I am interested in helping with the
implementation.
