Hi,
So is it wrong to rely on something like (if processor independence is
important):
<xsl:variable name="test" select="document('test.xml')/test"/>
<xsl:choose>
<xsl:when test="boolean($test)">
<xsl:apply-templates select="$test"/>
</xsl:when>
<xsl:otherwise>
<!-- error display -->
</xsl:otherwise>
</xsl:choose>
it works in saxon.
best,
-Rob

It might do that as an allowed recovery option but the default behaviour
is to issue a (possibly fatal) error. Unfortunately there's no way to
control that behaviour in XSLT itself.
xalan may have some implementation-specific customisation of this
though.
