Hello,

I would like to extract all paragraphs that have an attribute
of doc equal to contract. Instead I only receive the following
output and I was hoping to understand why?

<Template><Destination>
</Destination></Template>

Thank you very much
Rhonda



temp.xml
-------
<!DOCTYPE ProjectPlan [
    <!ELEMENT Template (Destination+)>
    <!ELEMENT Destination (Target+)>
     <!ELEMENT Target (Content+)>
        <!ATTLIST Target
              doc (contract | advice | plan) #REQUIRED
          >
    <!ELEMENT Content (#PCDATA)>
]>

<Template>
 <Destination>
  <Target doc="contract"/>
     <Para>CONTRACT para destined for output to contract.xml</Para>
 </Destination>
</Template>
.... other para's all with different doc value according to DTD


transform.xsl

<!DOCTYPE xsl:stylesheet>
<xsl:stylesheet

<xsl:template match="Destination">
  <xsl:element name="{name()}">
    <xsl:copy-of select="key('blueprint', '$contractType')"/>
