Please look at this screenshot:
Then look at "Mi cuenta" and "Crear una cuenta" links. As you see, those don't have templates defined, and in fact, when I saw the XML for layout, there is no en explicit template definition. so the question is, where is the default template for link defined?
I looked at module-theme/view/frontend/templates/link.phml but it seems it is not used.
Any help please?
