Re: [gobo-eiffel-develop] group task for geant

[Jocelyn <li...@dj...>]

May be we can not define a proper RND "define" for this "group"
but use it whenever needed with <element name="group" />
<element name="target">
...
    <zeroOrMore>
        <ref  name="tasks" />
        <element name="group">
            <zeroOrMore>
                   <ref name="tasks" />
            </zeroOrMore>
        </element>
     </zeroOrMore>
</element>

Except the RNG point, I guess we could try to have a notion of group in
geant ..
and then do not have a specific "group" task.

In my (test) code, the group task and command were almost empty ...
so we could create a GEANT_GROUP  and handle this for tasks, or even
group of options, group of .. whatever
