NOTES
...
If you're a fanatic about valid HTML and would like your templates to conform to valid HTML syntax, you may optionally type template tags in the form of HTML comments. This may be of use to HTML authors who would like to validate their templates' HTML syntax prior to HTML::Template processing, or who use DTD-savvy editing tools.
<!-- TMPL_VAR NAME=PARAM1 -->
In order to realize a dramatic savings in bandwidth, the standard (non-comment) tags will be used throughout this documentation.
