I'm trying to reproduce something like the following:

<compensatingcontrols xmlns ="http://www.namespace.net/schema.xsd">
  <compensatingcontrol>
    <id>4</id>
    <name>Control1</name>
    <description />
    <version />
    <source>Source Name</source>
    <controltext>Some control text.</controltext>
    <status>enabled</status>
    <validfrom>2007-08-03</validfrom>
    <expirationflag>neverexpires</expirationflag>
    <expiration>1900-01-01</expiration>
    <lastupdatedby>OWNER</lastupdatedby>
    <lastupdatedon>2007-09-17</lastupdatedon>
    <createdby>OWNER</createdby>
    <createdon>2007-08-03</createdon>
    <additionalinfo>
      <notes xmlns="http://www.namespace.net/schema.xsd" />
    </additionalinfo>
    <ownerinfo>
      <profile>
        <id>3</id>
        <profilename>OWNER</profilename>
      </profile>
    </ownerinfo>
  </compensatingcontrol>
</compensatingcontrols>

I can produce everything but the root @xmlns and the notes @xmlns attributes using the following query:

SELECT compensatingcontrol.ControlID AS 'compensatingcontrol/id'
 , compensatingcontrol.[Control Name] AS 'compensatingcontrol/name'
 , NULL AS 'compensatingcontrol/description'
 , NULL AS 'compensatingcontrol/version'
 , 'START' AS 'compensatingcontrol/source'
 , compensatingcontrol.[Control Description] AS 'compensatingcontrol/controltext'
 , 'compensatingcontrol/status' = 
  CASE compensatingcontrol.[Current?]
   WHEN 'True' THEN 'enabled'
   ELSE 'disabled'
  END
 , '2007-01-01' AS 'compensatingcontrol/validfrom'
 , 'neverexpires' AS 'compensatingcontrol/expirationflag'
 , '1900-01-01' AS 'compensatingcontrol/expiration'
 , 'GRMalone' AS 'compensatingcontrol/lastupdatedby'
 , '2007-06-01' AS 'compensatingcontrol/lastupdatedon'
 , 'GRMalone' AS 'compensatingcontrol/createdby'
 , '2007-01-01' AS 'compensatingcontrol/createdon'
 , NULL AS 'compensatingcontrol/additionalinfo/notes'
 , profile.EmpNum AS 'compensatingcontrol/ownerinfo/profile/id'
 , profile.EmpUserName AS 'compensatingcontrol/ownerinfo/profile/profilename'
FROM dbo.vwControls compensatingcontrol LEFT OUTER JOIN
 dbo.ProcessControl ownerinfo ON compensatingcontrol.ControlID = ownerinfo.ControlID LEFT OUTER JOIN
 dbo.vwProcessOwners [profile] ON ownerinfo.ProcessID = [profile].ProcessID
FOR XML PATH('')
 , TYPE
 , ELEMENTS XSINIL
 , ROOT('compensatingcontrols');

Thanks for your help! These namespaces are really giving me grief.
