[xsl] Saxon-EE 9.4.0.6 can't adress comment nodes

[bjoern.duenckel@xxxxxxxxxxxxxxxxxxx]

With Saxon-EE 9.4.0.6 I can't adress comment nodes.

   Source
   -----------------------------------------------
   <?xml version="1.0" encoding="UTF-8"?>
   <r>
        <!-- This is a comment. -->
   </r>
   -----------------------------------------------

   Stylesheet
   -----------------------------------------------
   <?xml version="1.0" encoding="UTF-8"?>
   <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
   version="2.0">
        <xsl:output method="text"/>
        <xsl:template match="/">
            <xsl:value-of select="count(//comment())"/>
        </xsl:template>
   </xsl:stylesheet>
   -----------------------------------------------

   Output with Saxon-EE 9.4.0.6
   -----------------------------------------------
   0
   -----------------------------------------------

   Output with Saxon-PE 9.4.0.6 (and any other Transformer I tried)
   -----------------------------------------------
   1
   -----------------------------------------------


Do you agree, that this is a saxon bug?
Or am I missing something about schema-awareness that would explain this 
behavior?
