htp on-line reference : <!---

syntax

<!--- comment --->



synopsis

This is a simple comment that is not included in the output. This can be very useful when commenting metatags as they are not included in the output either. Example:

<!--- This comment doesn't appear in the HTML file --->


Note that these comments should not include < or >, that is you should not use it to comment out htp code. For that purpose use something like this:

<if disabled_because_xyz>
  ...
</if>


Make sure that the variable is never defined and xyz should be the reason why you don't want to include this block
