Comment 1 for bug 1473541

This is a very important feature for translators, include me.

However, in my understand,

* other block tags (for example {% blocktrans %}, except for elif and else ) are not allowed inside a if tag [1],
* and other block tags (for example {% for %} or {% if %}) are not allowed inside a blocktrans tag [2].

So, I think we need think this over.
