Tom SW suggested a way to mitigate how verbose it is.

Another way -- perhaps not as neat conceptually, but not requiring you to 
have a fallback node, is simply not to use the xsl:choose. Since, as you've 
noted, you get no output if there is no ./currentStatus/comment, your logic 
is equivalent to:

<textarea rows="5" cols="40" name="comment" class="textbox">
  <xsl:value-of select="currentStatus/comment"/>
  <xsl:if test="not(currentStatus/comment)">No comments.</xsl:if>
</textarea>

Not so bad, eh?

Notice I've trimmed your './currentStatus/comment' to 
'currentStatus/comment' since they mean the same thing.

Others have addressed your getting the unwanted XML empty-element syntax. 
That's the real solution.

Cheers,
Wendell
