Sure, that's fine. The only problem that you'll find is that if you
get the *value* of the $logo variable, you'll end up with nothing,
because the img element that you create is an empty element and
therefore has no string value. You should instead use the xsl:copy-of
element to create a *copy* of the content of the $logo variable:

  <xsl:copy-of select="$logo" />

And that will insert the img element in your document.

(By the way, having a single xsl:when inside an xsl:choose is exactly
the same (but longer!) as having an xsl:if.)

Cheers,

Jeni
