Subject: RE: [xri] RE: Single delegation character


Title: Re: [xri] RE: Single delegation character
That's correct if you're using standard resolution. Dot means delegation in the xri-authority if you're using resolution as defined by the 1.0 spec because the semantics are defined by the resolution protocol.

I don't believe I have.  In the authority section (before the first
forward slash) dot means delegation.  Am I not correct?
