[xsl] Generating the xml: namespace from XSLT into a schema

[Danny Vint <dvint@xxxxxxxxxxxxxx>]

I have a stylesheet that builds a Schema. In this schema I need to output 
the xml:lang attribute on some elements in this schema. My stylesheet 
creates the schema import statement as well as creating the xml:lang 
attributes at the right place. The problem is I don't get a namespace 
declaration at the top of the schema which the IBM quality checker and MSV 
complain about. Here's what I get in the output:

<xsd:schema
	xmlns:xsd="http://www.w3.org/2001/XMLSchema";  	xmlns="http://www.ACORD.org/ 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
xmlns="http://www.ACORD.org/standards/PC_Surety/ACORD1.1.1/xml/";
		<!-- I need an xmlns:xml='xxx'  here to make this correct -->
	elementFormDefault="unqualified"
	attributeFormDefault="unqualified" 	targetNamespace="http://www.ACORD.org/s 
attributeFormDefault="unqualified" 
targetNamespace="http://www.ACORD.org/standards/PC_Surety/ACORD1.1.1/xml/"; 
version="1.1.1">
   <xsd:annotation>
      <xsd:appinfo>
         <version>1.1.1</version>
         <genDate>Sun Jul 14 11:03:53 EDT 2002</genDate>
      </xsd:appinfo>
   </xsd:annotation>
   <xsd:import namespace="http://www.w3.org/XML/1998/namespace"; 
schemaLocation="xml-ns.xsd">
      <xsd:annotation>
         <xsd:documentation>Get access to the xml: attribute groups for 
xml:lang
               </xsd:documentation>
      </xsd:annotation>
   </xsd:import><!--Start of Data types-->

....

      <xsd:complexType>
         <xsd:simpleContent>
            <xsd:extension base="C-255">
               <xsd:attribute ref="xml:lang"/>
            </xsd:extension>
         </xsd:simpleContent>
      </xsd:complexType>
   </xsd:element>
...
</xsd:schema>

And the stylesheet has this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
      xmlns:xsd = "http://www.w3.org/2001/XMLSchema";
      xmlns:xml="http://www.w3.org/XML/1998/namespace";
      xmlns="http://www.ACORD.org/standards/PC_Surety/ACORD1.1.1/xml/";
      xmlns:saxon="http://icl.com/saxon";
      extension-element-prefixes="saxon">

<!-- Adding this seems to cause problems with validation!
         xmlns="http://www.acord.org";
   -->

<xsl:output method="xml" indent="yes" />

...

<xsl:template match="/">

   <!-- START Schema Output -->

   <xsl:call-template name="notice"/>

   <xsd:schema>
   	<xsl:attribute name="elementFormDefault">unqualified</xsl:attribute>
   	<xsl:attribute name="attributeFormDefault">unqualified</xsl:attribute>
   	<xsl:attribute name="targetNamespace"><xsl:value-of 
select="$target"/></xsl:attribute>
   	<xsl:attribute name="version"><xsl:value-of 
select="ACORD-XML-DOC/@version"/></xsl:attribute>

      <!-- Information about the whole spec -->
   <xsd:annotation>
      <xsd:appinfo>
         <version><xsl:value-of select="ACORD-XML-DOC/@version"/></version>
         <genDate><xsl:value-of select="ACORD-XML-DOC/@genDate"/></genDate>
      </xsd:appinfo>
   </xsd:annotation>

	<!-- Support for the xml:lang attribute -->
	<xsd:import>
		<xsl:attribute 
name="namespace">http://www.w3.org/XML/1998/namespace</xsl:attribute>
		<xsl:attribute name="schemaLocation">xml-ns.xsd</xsl:attribute>
		<xsd:annotation>
			<xsd:documentation>Get access to the xml: attribute groups for xml:lang
               </xsd:documentation>
		</xsd:annotation>
	</xsd:import>

         <!-- If include_codes = no, then I need to include the external 
file -->
      <xsl:if test="$include_codes!='yes' and $code_types='yes'">
         <xsd:include schemaLocation="{$codelistfile}"/>
      </xsl:if>
      <xsl:apply-templates/>
   </xsd:schema>

      <!-- END Schema Output -->

</xsl:template>
