This revision

  * Admits "yzLN"/"yzLT" CTYPE codes for longitude/latitude axis pairs; it
    was felt that the 26 possibilities for "xLON"/"xLAT" would not be enough.

  * Augments the distortion function for the TAN projection to include 7th
    order terms.  This is sufficient to account for the complex distortions
    found in Schmidt plates.

  * Includes another header construction example, this one describing
    selenographic coordinates for an image of the moon.

Time is running out to make further comments!
