Representation of season was recently brought up again. In this case the question is whether hemisphere needs to be represented, see below.

My understanding is that the use case presented to us is satisfied, by using 21, 22, 23, 24 in place of month, to represent season.   While not a complete solution it seems to meet the concrete needs that were presented, even if it leaves unsolved some issues regarding sorting, when a season starts, etc. 

 There were other, less specific "potential" use cases presented, which could be satisfied by appending a qualifier to the season.  
    '2001-21' means "Spring, 2001"
     '2001-21q<xxx>' "Spring, 2001 qualified"  where <xxx> is the qualifier.
The qualifier could be a geographic location, but unless someone takes the initiative to try to develop this qualifier, it's specification won't be included in the spec.

This is where we ended up with this discussion, and as far as I knew everyone was satisfied.  Unless someone has a use case that this doesn't satisfy, I don't see a need to re-open discussion on this.  

Does anyone think this needs further discussion?
