That EN represents the language that the DTD is written in NOT the language of the document. The official DTD used in the official set of DOCTYPES for epub2 is written in English.

This in no way says anything about the language of the document itself. That is typically set using the xml:lang attribute on the html tag or alternatively by using dc:language metadata tag in the content.opf for the epub.

Stick with the official doctypes as specified for epub2 and epub3 and properly add your xml:lang attribute to any html tag or better yet, simply set the dc:language metadata.

See the wikipedia entry for doctype and more specifically the FPI here:
