Doesn't xsl:value-of look for the first text content all the way down the
whole branch?  If so, you could test like this:

<xsl:variable name='is-there-any-text'>
    <xsl:value-of select='.'>
</xsl:variable>

<xsl:if test='$is-there-any-text !=""'>....</xsl:if>

Or:

<xsl:if test="string(.)">....</xsl:if>

:->

Unfortunately, unless Matt has stripped whitespace, there may be some whitespace around to throw this off. So:

<xsl:if test="normalize-space(.)">....</xsl:if>

(But to avoid copying the empty nodes, Matt's going to have to traverse step-by-step only copying the ones that have non-empty string values ... no copy-of. Time for modes!)
