@JanelleJenstad, @sydb can you please have a look at this PR

Things I have checked:

• Counted all @type, looking for misfits (9 normal, 6 high-contrast; total 15)
• Counted all @subtype, looking for misfits (6 high-res, 6 low-res, 3 thumbnail; total 15)
• Extracted all @url looking for misfits by eye.
• Counted each of the following strings in the values of @url:
  • spi: 15
  • contrast: 6
  • normal: 6
  • thumb: 3
  • [above 3 add up to 15]
  • highRes: 6
  • lowRes: 6
  • [above 2 add up to 12, the # of non-thumbs]
  • 001v: 10
  • 001r: 5
  • detail: 5
  • [above 3 add up to 15]
• Ran most of the build (make clean validate html-web test exemplars) on this branch: no sigficant errors or failures.

As for the word “normal”, it is what I have heard photographers use to refer to the images that have not had contrast boosted.

The only thing I question is the @source of "#UND" — is this not a made-up example? (In which case "#NONE".) I do not remember, maybe this was based on something real.
