Hi,
I am an Emilian speaker and eml Wiki user. the eml code is obsolete according to ISO, but I find it better than using split egl and rgn codes, or even using just egl (very offensive and disrespectful to Romagnol people). Linguists today find Emilian and Romagnol separate languages, when there are other tongues objectively further to each other, but considered dialects of the same language, like Maghreb Arabic and Yemenite Arabic: at times mutually unintelligible but paradoxally considered part of the same language. Emilian and Romagnol have a high rate of mutual intelligibility, and they are almost never mutually unintelligible if not for literally a bunch of words.
