As the template is rendered before the form is shown, it cannot validate
form input.

If you can assume that the users' browsers are HTML5 compliant (a
reasonable assumption these days), then the input element may be given a
"pattern" attribute.

<input type="text" id="listname" name="listname" size="30" value="[%
saved.listname %]" pattern="[0-9A-Za-z][-+._0-9A-Za-z]*-[Ll]" />

For more details about client-side form validation, see this article
in MDN:
