Re: [plasma] S/MIME Capabilities

Just to be clear, you are suggesting that an attribute defined by which a
sender says "I understand Plasma" just like there is one which says I
understand inner binary.  Recipients could then store this attribute as part
of the senders capabilities.  

This is totally trivial and yes we should do it.  I assume that this would
just be a "binary" value - I do or do not support it.  If a new version of
Plasma ever comes into existence then a new attribute with a different OID
value would be created.  There is no need to talk about algorithms or
advance vs basic here.
