Automatically translated message ids
Plone will automatically perform translation for message id objects which are outputted in page templates.
The following code would translate my_translateable_text to the native language activated for the current page.
<span tal:content="view/my_translateable_text">
Note that since my_translateable_text is zope.i18nmessageid.message.Message containing its own gettext domain information, the i18n:domain attribute in page templates does not affect message ids declared through message factories.
