Namespaces and XSD

Hi,
  I've been using DTDs with my XML for years. Now I am trying to replace one
of my DTDs with an XSD. I've been told that the root element of the XML I am
outputting from an XSLT transform should have a namespace that corresponds to
the targetNamespace of my schema.

  So far so good. I output the root element with the namespace. But now some
of the child elements are being output with xslns="". I've tried everything I
can think of to eliminate this extra namespaces from being output. (I am
running SAXON EE and using XSLT 2.0)

  I've tried adding xpath-default-namespace= to the value of the
targetNamespace. I've tried it with "". Neither work.
  I've tried replacing generized template matches, using copy, with specific
templates that specify which attributes to output.

  I finally removed the namespace from the root element so it's not output
anymore. Now I have no extraneous namespaces in my output. But, how will the
output XML file know which schema defines it?

  How can I get rid of the unwanted namespace?

  Is there another way to reference the schema (XSD) from the XML document
without adding a namespace to the root element?

Thanks,
  Craig

  Here's a snippet of the XML source file I am transforming:
<?xml version="1.0" encoding="UTF-8"?>
<!--Arbortext, Inc., 1988-2012, v.4002-->
<!DOCTYPE refDictEntry PUBLIC "-//SAS//DTD authoring 13.0//EN"
"authoring.dtd">

axLevel>
</syntaxSimple>

Here's the title template so you can see I am doing nothing to output a
namespace:
<xsl:template match="title[parent::refDictEntry]">
  <title>
    <xsl:choose>
      <xsl:when test="string-length(substring-before(normalize-space(.),'
'))=0">
        <xsl:apply-templates/> <!-- no word space found so assume only one
word in title -->
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="substring-before(normalize-space(.),' ')"/> <!--
get first word in title -->
      </xsl:otherwise>
    </xsl:choose>
  </title>
</xsl:template>



  Here's a snippet of output with no namespace on the refDictEntryCjollection
root element:
<?xml version="1.0" encoding="UTF-8"?>
<refDictEntryCollection eid="n1ewuqnosopv1kn1vx2dx8l3rchi" xml:lang="en">
   <refDictEntry eid="p0xkrj83an7dknn1sgukpmnphcje"
                 type="function"
                 xml:lang="en"
                 docAlias="lefunctionsref">
      <?myURI

      <title>ABS</title>

            <syntaxLevel>
               <keyword>


  Here's the same snippet when I put the namespace on the root element. Notice
the title, shortDescription, summary and syntax elements now have null
namespaces.
<?xml version="1.0" encoding="UTF-8"?>
<refDictEntryCollection
xmlns="http://www.sas.com/xml/namespace/sas_doc_xis_refDictEntryCollection-1.
0"
                        eid="n1ewuqnosopv1kn1vx2dx8l3rchi"
                        xml:lang="en">
   <refDictEntry eid="p0xkrj83an7dknn1sgukpmnphcje"
                 type="function"
                 xml:lang="en"
                 docAlias="lefunctionsref">
      <?myURI

wer.htm#p0xkrj83an7dknn1sgukpmnphcje.htm?>
      <title xmlns="">ABS</title>
      <shortDescription xmlns="">Returns the absolute

      <summary xmlns="">
         <category>Mathematical</category>
      </summary>
      <syntax xmlns="" eid="p07w43trquf74on1ct3ur17des7e">
         <syntaxSimple eid="p005cpxu5su0dkn1b6to129kl254">
            <syntaxLevel>
               <keyword>


  And finally here's the title element defined in the schema:
       <xs:element name="title">
              <xs:complexType mixed="true">
                     <xs:choice minOccurs="0" maxOccurs="unbounded">
                           <xs:element ref="statValue"/>
                           <xs:element ref="subscript"/>
                           <xs:element ref="superscript"/>
                           <xs:element ref="userSuppliedValue"/>
                           <xs:element ref="windowName"/>
                     </xs:choice>
              </xs:complexType>
       </xs:element>
