language versus html markup?

Especially for emails I have used special parsing with translations, here is the body only (not full HTML) of a password-recovery message with translations:

Code:

<p>
    <i18n replacement="{{username}}">start_with_hello</i18n>
    <br />
    <br />
    <i18n>reset_password_request_received</i18n>
    <br />
    <br />
    <i18n>reset_password_instructions</i18n>
    <br />
    <a href="{{password_reset_url}}">{{password_reset_url}}</a>
</p>

First I applied Mustache parser, second I applied a parser that uses $this->lang->line() for translating the i18n tags. The idea was from here: https://devzone.zend.com/1441/zend-frame...anslation/

This is an exotic way, probably not interesting for you.
