[xsl] XSLT 2.0 contains question

[David Carver <d_a_carver@xxxxxxxxx>]

Under XSLT 1.0, I can do the following to filter out any xsd:element 
that has a xsd:documentation element that has the word "Deprecated" in it.

   <xsl:template match="xsd:schema">
       <xsl:copy>
           <xsl:copy-of select="@*"/>
          
           <xsl:for-each select="xsd:element | xsd:complexType">
               <xsl:if 
test="count(xsd:annotation[contains(xsd:documentation, 'Deprecated')]) = 0">
                   <xsl:apply-templates select="."/>
               </xsl:if>
           </xsl:for-each>
       </xsl:copy>
   </xsl:template>


However, under XSLT 2.0, I get an error because contains can't take a 
more than xsd:documentation element.   What is correct way to handle 
this under XSLT 2.0.
