Used to insert short comments in your application files. This tag is similar to the <@COMMENT> meta tag, except the comment goes inside the required attribute COMMENT, rather than between the <@COMMENT> and </@COMMENT> tags.
The tag and its contents are not returned the browser and any meta tags in the COMMENT attribute are not processed.
The attributes of this tag must obey all the quoting rules specified in Quoting Attributes; for example, if the COMMENT attribute contains spaces, you may not omit the quotes surrounding the attribute value.
<@! COMMENT="Here is a comment.">
<@! "This code was written by Fred on 5/4.">
<@COMMENT> </@COMMENT>
<@EXCLUDE> </@EXCLUDE>
