Your understanding is correct.

I have now implemented a 2-argument form of the function (the full
7-argument form will have to wait for next weekend).

The following output:

transformAt line 33 in file://localhost/home/colin/gobo/src/gexslt/transformation.xsl#test2:
Fatal error: http://www.w3.org/2005/xqt-errors#FOER0000: error generated by test of gexslt:transformation

   Found an error

is produced by this transformation:

    </output>
   </xsl:template>
  </xsl:transform>
 </test2>
</test:transformations>

<xsl:output method="text"/>

<xsl:template name="initial" >
  <xsl:variable name="transformation_result" select="gexslt:transformation('#test1', doc(''))"/>
  <xsl:value-of select="$transformation_result/output/text()"/>

  <xsl:variable name="transformation_result_2" select="gexslt:transformation('#test2', doc(''))"/>
  <xsl:if test="count ($transformation_result_2) gt 1 and $transformation_result_2[1] instance of xs:QName">
   Found an error
  </xsl:if>
</xsl:template>

</xsl:transform>

Note there have been some changes to the spec.

In particular, on an error, the output is now: (QName, description, error-objects...)

If no error, only the principal result document is output. This is
because, for xsl:result-document, I cannot capture the output with my
current architecture, as, int the case of file output at least, the
output is streamed directly to the file.

I might think about that one.
