question about bagID

I have a couple of questions about that rdf chunk

<rdf:Description about"http://h/p" bagID="B01">
  <dc:Creator rdf:parseType="Resource">
    <name>Pierre-Antoine</name>
    <email>champin@cpe.fr</email>
  </dc:Creator>
</rdf:Description>

how many triples should be reified and put in bag B01 ?
Only the first level triple (dc:Cereator, http://h/p, #genid1)
or also sub-triples (name, #genid1, "Pierre-Antoine") and (email, #genid1, "champin@cpe.fr") ?

in other words, must reification by bagID be shallow or recursive ?

my answer is that it should be recursive,
but I think that SiRPAC is doing it shallow.
