<itemizedlist mark="bullet">
<listitem>Bit 1 permits read access.</listitem>
<listitem>Bit 2 permits write access via SPARUL and it's basically useless without bit 1 set.</listitem>
<listitem>Bit 4 permits write access via "RDF sponge" methods and it's basically useless
without bits 1 and 2 set.
</listitem>
<listitem>Bit 8 allows to obtain list of members of graph group; an IRI can be used as graph
IRI and as graph group IRI at the same time so bit 8 can be freely combined with any of bits
1, 2 or 4.
