Hello, I wanted to know if it is possible that they would solve a doubt that I have to apply on my website created in Magento. Specifically on the html tag and the possibilities in the "lang".
Right now I have this tag:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="es" lang="es">
But I want to change the "es" (Generico) to "es-es" (from Spain).
I already know that the tag lang="is" can happen without problem lang="is-is" but my question is if in the tag "xml: lang" I can apply the same change or I will create some problem in Magento.
My idea is to leave it in the following way:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="es-es" lang="es-es">
is it possible?
