(I18n) Missing hreflang attribute #1488
Description
The i18n self test says:
Attributes that express the language of external resources should not use the HTML
langand XMLxml:langlanguage attributes, but should use a different attribute when they represent metadata (which indicates the intended use of the resource rather than the language of a specific range of text). more
This may be relevant for the link element. Should we add a hreflang attribute (like in HTML)?

Dave Cramer: 1488
… missing
hreflangattribute… see issue
… there is a PR from Matt
See github pull request #1497.
Dave Cramer: PR 1497
… this is designed for the links in the package file
… if we're linking to external metadata, we can determine the language of the file
… consistent with other vocabularies
… this would be new, and wouldn't break anything
… any comments?
Ben Schroeter: Trying to understand the usage of this?
Dave Cramer: Say you have a multi-lingual epub, multiple metadata records
… norwegian canadian dictionary that has one record in norwegian and one in canadian english
… if the UI is set in one language, it can know to present the correct metadata to the user
… the RS doesn't have to determine the vocab from the resource, it can determine before download
… a hint
Ben Schroeter: Ok
Dave Cramer: I'm not aware of a RS that does this
Brady Duga: You can link to external metadata records? /sarcasm
Dave Cramer: We can write a test for it, but no RS will test it
Ben Schroeter: And where will you find a Norwegian-Canadian dictionary...
Brady Duga: This PR does add another untestable conformance requirement
Dave Cramer: I feel we're a little bit stuck here
… it's an i18n best practice
… if we say we're going to have linked metadata, we should have this
… we put this in, we get tests, the concept gets marked as at-risk at CR
… I think we should accept the PR, then see what testing shows us
Dave Cramer: Progress!
… on i18n issues at least
… thanks everyone
Dave Cramer: see you all in the comment section

I do not like the hreflang attribute. Metadata or HTTP headers for the referenced contents should specify the used language.
I know that this is not always possible. But hreflang is not a solution but a hack.
