[Hal Rosenstock]

Hi Eitan,

The component masks are also significant relative to the below. See 
embedded comments.

This is a join rather than a create. It relies on the group preexisting
or is rejected by the SA.

This is a request for group creation with sufficient components for
this.

This interpretation is non conformant with o15-0.2.1 (IBA 1.2) which
obsoleted 015-0.1.2 (IBA 1.1). It is supposed to be rejected with
ERR_REQ_INVALID.

JoinState bit 0 is Full Member. Wouldn't 0x1 have bit 0 on making this a
full member join ? Anyhow, looking at the components, this appears to be
a join rather than create requests (although the component mask is not
shown).
