Does Photoshop Elements 12 Support the MWG Face Region Metadata Standard?

Question

I'm looking at the trial version of PhotoShop Elements 12. I see that it is possible to use the Organizer to automatically recognize faces and to manually define Face Regions in images.
These then appear as People Tags in the Organizer.
However, if I save the Metadata to the file, People Tags just seem to be added as IPTC/Core Keywords. I was hoping that PE12 would at least support the Metadata Working Group's Face Region standard, and that People Tags would be saved as XMP using the MWG-RS schema.
Would someone more familiar with PE12 please confirm whether PE12 does or does not support the MWG standard?
If it doesn't support it, then that's a disappointment, particularly considering the standard has been around since November 2010, and that Adobe is a founding member of the Metadata Working Group.

Answer 1

The point about whether to use an automatic process or not is a separate issue. I can understand that some people would not want to use it. However, even doing it manually in PE12 does not use the MWG standard.
Thanks for the pointer to the thread, which I note was started 2 years ago, with the last comment a year ago.
From that, I draw the conclusion that the PE developers see this as a very low priority. All the more reason for me to look at competitor products that do support this standard (e.g. Picasa and Photo Supreme).
Thanks again.
