Ron's post brings up one scenario I can think of, but I have definitely 
encountered other times when xsl:if has come in handy. In my reply to 
Phlip, I mentioned that thing that was troubling me wasn't so much that 
there was conditional logic in the outputting code, but that the code 
was outputting presentation elements instead of pure data.

I would much rather see out of our code:

<title><highlight color="hotpink">The title</highlight></title>

then

<title><span style="background-color:hotpink">The title</span></title>

(outside the whole hotpink thing)

The reason is that we often have to create data structures that are in 
turn processed for both web, mobile and pocket PC devices, and rather 
than have to modify the outputting code, I would rather modify the 
stylesheet.

Actually, thinking about it more, I would rather see

<title highlight="hotpink">The title</title>

That way XSLT sheets can determine if they want to use it or not, but 
the other sheets don't ever have to be aware of it. Using the highlight 
color as an attribute of the title means that we only have to have the 
xsl:if statement on those sheets that actually care about it.
