Yes.

Thanks for the sample ACDSee XMP file. The next release of exiftool will have the ability to write XMP-acdsee:rpp.

You may want to submit a bug report to ACDSee: They are incorrectly using a tag ID of "exif:FocalLengthIn35mmFormat" instead of "exif:FocalLengthIn35mmFilm" (but their track record is much better than Microsoft, who made two such naming errors in addition to four case errors in XMP tag ID's).

Aside: Software vendors should really ask me to validate a sample of their meta information (not only XMP, but EXIF as well) before they release it to the public. I will do this for free, and it will save a lot of hassle trying to maintain backward compatibility with incorrectly formatted meta information. I can spot some problems immediately that may otherwise remain for months or years before they are fixed, and by then it is too late.
