Hi 
i want to prefix namespace as ns0 , 
my procedure is …i have one xml schema file, that schema file i am adding in 
word 2003 using xml sturture panel. now from that xml schema i am adding 
placeholders in word document. and then save the document as .xml (wordml).
following is example of schema file
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="DocumentSchema" 
targetNamespace="http://tempuri.org/DocumentSchema.xsd" 
elementFormDefault="qualified" xmlns="http://tempuri.org/DocumentSchema.xsd" 
xmlns:mstns="http://tempuri.org/DocumentSchema.xsd" 
xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="Root">
…..
…..
</xs:schema>
so after saving xml document if will open that document in notepad and it 
will look something like
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<?mso-application progid="Word.Document"?>
<w:wordDocument 
xmlns:w="http://schemas.microsoft.com/office/word/2003/wordml" 
xmlns:v="urn:schemas-microsoft-com:vml" 
xmlns:w10="urn:schemas-microsoft-com:office:word" 
xmlns:sl="http://schemas.microsoft.com/schemaLibrary/2003/core" 
xmlns:aml="http://schemas.microsoft.com/aml/2001/core"

xmlns:ns0="http://tempuri.org/DocumentSchema.xsd" w:macrosPresent="no" 
w:embeddedObjPresent="no" w:ocxPresent="no" 
xml:space="preserve"><o:DocumentProperties><o:Author>hshah1</o:Author><o:LaLines><o:Paragraphs>1</o:Paragraphs><o:CharactersWithSpaces>26</o:CharactersWithSpaces><o:Version>11.6359</o:Version></o:DocumentProperties><w:fonts><-……………………

w:space="708"/><w:docGrid 
w:line-pitch="360"/></w:sectPr></wx:sect></w:body></w:wordDocument>

now all namespace is store as ns0, which is ok for me but If change  schema 
from tempuri.org to abc.com .. like following
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="DocumentSchema" 
targetNamespace="http://abc.com/DocumentSchema.xsd" 
elementFormDefault="qualified" xmlns="http:// abc.com /DocumentSchema.xsd" 
xmlns:mstns="http:// abc.com /DocumentSchema.xsd" 
xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="Root">
…..
…..
</xs:schema>
then follow all the procedure from beginning like .
Remove schema file and then close the word document , again open and add 
schema file , add few placeholders using schema file , save document as 
.xml(wordml) And if  will open that xml file in notepad it change namespace 
with ns1 or ns2 or ns3
Something like following ..
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<?mso-application progid="Word.Document"?>
<w:wordDocument 
xmlns:w="http://schemas.microsoft.com/office/word/2003/wordml"
