| If I understood it correctly:
| 
| <dtml-if X>
|  <a href="a_url">
| </dtml-if>
|  link text
| <dtml-if X>
|  </a>
| <dtml-else>
|  (no link currently available)
| </dtml-if>
| 
| 
| Or alternatively:
| 
| <dtml-if X>
|  <a href="a_url">link text</a>
| <dtml-else>
|  link text (no link currently available)
| </dtml-if>

Or sometimes you just need to rethink what "clean" is... and
where you want clean, and where you're willing to be a little dirty.

<dtml-call "REQUEST.set('link_url','')">
<dtml-call "REQUEST.set('link_end','(no link currently available)')">

<dtml-if X>
<dtml-call "REQUEST.set('link_url','<ahref=a_url>')">
<dtml-call "REQUEST.set('link_url','</a>')">
</dtml-if>


<dtml-var link_url>link text<dtml-var link_end>

I would do it this way, if I could pre-set that text in an earlier
<dtml-call> and the programming logic, would mess up my display flow,
it works nicely for <dtml-in> where you have a list of URL's, and you
can hide the ugliness in another place.

<dtml-in 'url-list'>
    <dtml-call "setLinkText(REQUEST)">
    <dtml-var link_url>link text<dtml-var link_end>
</dtml-in 'url-list'>
