Hi Shadi,

I thought this might be a bit outside the core focus of EARL.

We will probably use dc:language as an application specific extension to
earl:TestSubject, in a similar way as outlined below, since that at
least will not break anything.

We also plan to record http content-language for the web resource involved.

Regards,
Nils
