Problem: The syntax of #if directive is hard to read (especially it is hard to read and understand for nontechnical users and especially in the case of nested directives).

I propose to introduce an alternative syntax for #if directive, having separate open and close tags.

Possible syntax:

<div if="condition">
...
</div>

or maybe

<if condition="...">
...
</if>

It is especially useful for excluding a part of an included template. (Yes, I know about <noinclude> directive, but it is not enough flexible to in/ex-clude parts of a page separately.)
