[OSGeo-Discuss] Input regarding Axis Order Confusion

I was starting to get lost in this thread but what Paul wrote summarizes 
my thinking very well: 1.3 brings no real new value for interoperability 
except making ISO happy and making things more complicated. That being 
said, we will probably support WMS 1.3 in MapServer sooner than later, 
even if it's just from completeness.

Sorry for not jumping in earlier Arnulf. I have already spent too much 
energy talking about this 1.3 fiasco in the past and didn't feel I had 
much to add.

BTW, I think there was going to be a discussion on this issue at this 
week's OGC TC meetings. Can someone who was present please summarize 
what came out of that discussion?
