ok, have that locally already, anyway, wrt the xml, I'm not sure we shouldn't instead have the default ones separated, since these are mandatory, something like:

<concurrent>
  <default-managed-thread-factory + all attrs except name and context-service />
  <default-managed-executor-service + all attrs except name and context-service />
  <default-managed-scheduled-executor-service + all attrs except name and context-service />
  <managed-thread-factories/>
  ...
</concurrent>

Wdyt?

I'm also adding the "concurrent" as an boolean attr to root, with false as default value. Only if true the EE concurrent related DUPs are added...
