Well, Doug White asked for documentation. When it comes to the Gigabit
Ethernet, I believe the IEEE standards are about as authoritative as you
can get.

If you check the specs for some of the Intel Gigabit Ethernet cards,


you'll see that they refer to 100base-TX, but 1000base-T.

So I stand by my claim that 1000base-T is clearly more correct than
1000baseTX. It would be nice to get this fixed - however, it is a
minor point and I certainly believe that there are other tasks that
are more important.
