Re: Filtering, xslt 2.0

I suspect it is a shell issue (Using Bash on Linux)
Test case
<?xml version="1.0" encoding="utf-8"?>
<set>

   <data>
     <name>A</name>
     <type>dog</type>
   </data>
   <data>
     <name>B</name>
     <type>cat</type>
   </data>
   <data>
     <name>C</name>
     <type>mouse</type>
   </data>
</set>

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:d="http://www.dpawson.co.uk/ns#"

  version="2.0">

<xsl:param name="types" as="xs:string"/>

If you declare the type as a single string item, then it doesn't make
sense to attempt to use the "?param-name" syntax further below to pass
in an XPath expression evaluating to a sequence of strings.

<xsl:strip-space elements="*"/>

<xsl:template match="set">

<xsl:message>
    <xsl:value-of select='$types'/>
  </xsl:message>

     <xsl:for-each select="data">
       <xsl:sort select="name"/>
       <xsl:apply-templates/>
     </xsl:for-each>
   </xsl:template>

   <xsl:template match="data">
     <xsl:if test="type = $types">
       <xsl:apply-templates mode="pass"/>
     </xsl:if>
     <xsl:if test="contains(concat(',', $types, ','), concat(',', type,

       <xsl:message>
    <xsl:value-of select="'Dimitre'"/>
       </xsl:message>
     </xsl:if>
   </xsl:template>

<xsl:template match="name|type" />

   <xsl:template match="name|type" mode="pass">
     <xsl:apply-templates/>
   </xsl:template>

    <xsl:template match="*">
   <xsl:message>

     </xsl:message>
</xsl:template>

</xsl:stylesheet>

1. sax2 seq.xml seq.xsl op.xml ?types='("A", "B")'
Errors with Unrecognized option: "B")

2. sax2 seq.xml seq.xsl op.xml ?types="('A','B')"
XPTY0004: A sequence of more than one item is not allowed as the value
of variable $types
   ("A", "B")
