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 using Jay's proposal:

<dtml-if X>
 <a href="a_url">
 <dtml-always>
  link text
 </dtml-always>
 </a>
<dtml-else>
 (no link currently available)
</dtml-if>

I don't really think this is an improvement.


As for <dtml-then>, of course it should be </dtml-else>
instead. It's hard to see the point here, and there is no point
at all if there isn't a dtml-always (except for XML
nitpickness); but with dtml-always there _may_ be a point.

<dtml-if X>
 foo
 <dtml-always>bar</dtml-always>
 zoo
 <dtml-else>
  goo
  <dtml-always>mar</dtml-always>
  moo
 </dtml-else>
 woo
  <dtml-always>far</dtml-always>
 boo
</dtml-if>

This will render either:

when X is true:
 foo bar zoo mar woo far boo
when X is false:
 bar goo mar moo far

So suddenly order starts mattering.

It's a rather convoluted way of achieving this results, but
there may be situations where this is useful. I don't know.
