One possible (pragmatic) solution is to replace your last line

tree.write(file, xml_declaration=True)

with

with open(file, 'wb') as f:
    f.write(b'<?xml version="1.0" encoding="UTF-8"?>');
    f.write(b'<!DOCTYPE email-template PUBLIC "-//yourcompany, Inc.//DTD email-template//EN" "email-template.dtd">')
    tree.write(f, xml_declaration=False, encoding='utf-8')
