 Hello everone,

 I started to play with XSLT 3 accumulators and am not sure I
 understand the specifications correctly with regards to the order of
 accumulator rules.

 Take the following example:

 <xsl:transform version="3.0"
               xmlns:xs="http://www.w3.org/2001/XMLSchema";
               xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <xsl:output method="text"/>

  <xsl:mode on-no-match="shallow-skip" use-accumulators="#all"/>

  <xsl:accumulator name="accumulator" as="xs:integer" initial-value="0">
    <xsl:accumulator-rule match="element">
      <xsl:sequence select="1"/>
    </xsl:accumulator-rule>
    <xsl:accumulator-rule match="element">
      <xsl:sequence select="2"/>
    </xsl:accumulator-rule>
  </xsl:accumulator>

  <xsl:template match="/">
    <xsl:apply-templates/>
    <xsl:sequence select="accumulator-after('accumulator')"/>
  </xsl:template>
 </xsl:transform>

 And apply it to the following document:

 <element/>

 From my reading of the specs I would expect value of the accumulator
 to be 2 because both rules match the element node and the rule
 selecting 2 is last in document order. But this stylesheet returns 1
 when I run it with Saxon EE 10.1.

 This seems to be a bug in Saxon, doesn't it?

 Best,
