I want nothing to show up in the textarea. This suggestion actually puts the
<!-- comment --> in the textarea which is worse.

You could generate a comment in your result instead of a space:

<textarea name="comments" cols="50" rows="5" class="bodytext">
   <xsl:comment> x </xsl:comment>

Such a comment (or processing instruction) is a common workaround when 
targeting HTML or SGML systems that don't like XML empty-element syntax.

But since you didn't say why you need to trim the space I can't say if this 
is actually an improvement.
