Topic on Extension talk:Variables

Variables is not involved into HTML sanitization, out of scope.

If template contains:

<nowiki><!-- this is a comment --></nowiki>

then the whole thing gets rendered as visible text on the host page.

If template contains:

<!-- this is a comment -->

then none of it gets transcluded.

Really just want to put some invisible text on the host page-- doesn't have to be an HTML-comment.

This doesn't get transcluded either:

<span style="display:none">Hidden Span</span>
