Ok, Arnold,
  I just want to say that there are good reasons to refer to either
component independantly. It was difficult with the list up to now.

<Hm.  Frankly, it should not be taken as an excuse to rip 2-D and 3-D
<coordinates apart.  One needs to characterize the vector, not the
<vector components.
