To clarify:

It is my understanding that using the "EPSG:4326" forces the assumption
that the ordering is y, x. This understanding is based on feedback from
conversations at FOSS4G2007, the most memorable of which was with Raj
(from OGC), who essentially told me (as far as I remember) "You can't do

I have no idea what "You can't do that" means. The letters EPSG mean
nothing special to me, and to claim that they do seems weird to me. 

Given that, I have no particular opinion of my own basd on my own
knowledge. However, it appears to be a not-uncommon opinion that using
the EPSG code in this way would be 'bad form'. 

Or maybe I really just misunderstood, and this should have all been
resolved 6 months ago.

I don't know enough to have any personal prference: my understanding is
based entirely on what I have been told, and there is no significant
support for what I have been told that I am able to point to.
