Error in xml file validation to its relevant xml schema

Question

Hi All,
I have 3 xml schema files files from which I generated a XML file using PLSQL.I am getting this error when I am trying to validate xml file to the schema:
*'WMWROOT' NOT DECLARED*.Can anyone help me with this,I am including the main schema file and also the XML generated.
XML Schem file:
Itemdownload.xsd:
<?xml version="1.0" encoding="utf-8" ?>
<xs:schema id="ItemDownload" targetNamespace="http://www.manh.com/ILSNET/Interface" elementFormDefault="qualified"
     xmlns="http://www.manh.com/ILSNET/Interface" xmlns:xs="http://www.w3.org/2001/XMLSchema" version ="2007">
     <xs:include schemaLocation="Item.xsd" />
<xs:element name="WMWROOT" nillable="true" type="WMWROOT" />
<xs:complexType name="WMWROOT">
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="1" name="WMWDATA" type="WMWDATA" />
</xs:sequence>
</xs:complexType>
<xs:element name="WMWDATA" nillable="true" type="WMWDATA"/>
<xs:complexType name="WMWDATA">
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="1" name="Items" type="ItemList" />
</xs:sequence>
</xs:complexType>
<xs:element name="Items" nillable="false" type="ItemList" />
<xs:complexType name="ItemList">
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="unbounded" name="Item" nillable="true" type="Item" />
</xs:sequence>
</xs:complexType>
</xs:schema>

<?xml version="1.0" ?>

Hey,
As you said I tried keeping the namespace in xml file and it worked for a strange reason I am getting the same error again,I am not able to figure it why!!
The error is:
SAMPLEITEMDLFILE.xml:2,139: no declaration found for element 'WMWROOT'
The XML document SAMPLEITEMDLFILE.xml is NOT valid (1 errors)
This is the part of PL/SQL code thru which I am generating the xml:
UTL_FILE.put_line (l_out_file, '<?xml version="1.0" ?>');
UTL_FILE.put_line (l_out_file, '<WMWROOT');
UTL_FILE.put_line (l_out_file, 'xmlns="http://www.manh.com/ILSNET/Interface"> ');
UTL_FILE.put_line (l_out_file, '<WMWDATA>');
UTL_FILE.put_line (l_out_file, '<Items>');
I am validating it in stylus studio tool.
Can you please help me thru this?
