depthy.me doesn't recognize depth information in image

[boardhead]

depthy.me doesn't recognize the depth information in the attached image. The metadata in this image is identical to an image I found that works with depthy with the exception that the XMP has been restructured to use long-hand format, and the order of some xmp properties has been changed. But neither of these changes should make a difference. Somehow it seems that depthy may incompatible with long-hand XMP format (which is written by many metadata apps).

I've run some more tests, and depthy still doesn't like this XMP if I change it to shorthand format. So it could be something about the ordering of the XMP properties that is causing the problem. But according to the XMP specification, the ordering of the properties shouldn't matter.

Another possible difference is that single quotes are used in the XMP instead of double quotes. Both are allowed according to the XMP spec.

I haven't yet been able to narrow down the exact reason for the problem.
