Interesting, I never had to use one so I guess my perception is skewed (all
common italian projected
systems are in E/N order, so do all of the USA ones I've worked with so
far).
Let's check on the database itself (I was not referring to the INSPIRE case,
but in general).
I created a little program, attached, that scans the EPSG database in its
natural order and
checks all the projected CRS, seeing what their axis order is.

The result confirm what you said, 30% of the projected SRS in the official
database, v 7.5,
is indeed in North/East order:

total: 3522
north/east: 1068
unknown: 41

Do you know why this order is preferred? Really makes no sense to me (this
is not boat/aircraft navigation)

Cheers
Andrea
