I am still gettng the same error. The xml file is now
<?xml version="1.0" encoding="UTF-8"?>
<CUSTOMER xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="" ID="568945">
<FIRSTNAME>Arnold</FIRSTNAME>
<LASTNAME>McEriccson</LASTNAME>
<ADDRESS>
<LINE1>31, Nomadic Avevnue</LINE1>
<LINE2>Pasadena Clove</LINE2>
<CITY>WoolTown, MT</CITY>
<ZIP>45263</ZIP>
</ADDRESS>
<BIRTHDATE>1967-08-13</BIRTHDATE>
</CUSTOMER>
The xsd file is:
<?xml version="1.0" encoding="UTF-8"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="CUSTOMER">

<xs:sequence>

<xs:sequence>
<xs:element name="LINE1" type="xs:string"/> <xs:element name="LINE2" type="xs:string"/> <xs:element name="CITY"/>
<xs:element name="ZIP" type="xs:int"/> </xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="BIRTHDATE" type="xs:date"/> </xs:sequence>
<xs:attribute name="ID" type="xs:double"/> </xs:complexType>
</xs:element>
</xs:schema>
There seems to be something fairly obvious that i am missing.
