XEP-0080: Add "regioncode" element.

No description provided.

Notes:

• I'm not one of the author of the XEP.
• The XEP is stable, but the new field is optional, so it's backward compatible and should be fine to add.

@stpeter this change needs author acceptance, and you're one of them (I don't have the nickname of Joe Hildebrand to ping them too). Would you mind checking it? Thanks!

[stpeter]

LGTM. It would be nice to add the mapping to other formats in Table 2. (Alternatively, we could remove the section about mappings, since I expect that some of those formats are obsolete.)

@hildjj do you have opinions?

[hildjj]

I have no objection. Are all of the formats in Table 2 obsolete now? Did vCard XML ever get traction?

Thanks for your quick feedback.

XEP-0054 is still in use and even in compliance suite, while several clients have been moving to XEP-0292 (probably supporting both).
To be honest, I don't know how I would map this field to the formats in mapping as at least vCard-XML seems to use free form region, not something standardized such as ISO 3166-2. Maybe removing this entire section is the best thing to do indeed.
