If we make ai18n-enabled form then this approach can be a problem as we
should have translations for all the possible cases and values. Haven't yet
time to investigate the possibilities better, but I think that one can use
dictionary keys instead of a real message, e.g.:

<rule context="/email">
    <assert test="contains( string(.),'@')">
        error.email.wrongformat
    </assert>
</rule>

and have a translation like this in dictionary:
<message key="error.email.wrongformat">Wrong email format. Email should look
like {0}.</message>

then have this in the form:
<i18n:translate>
    <i18n:text><xf:violation ref="/email"/></i18n:text>
    <i18n:param>user@hostname.com</i18n:param>
</i18n:translate>

The other problem here would be to know what are the needed params for a
particular case.
