Redefine xs:element

[JuliusIT]

I have a problem redefining the xs:element in this way:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema"[/URL] xmlns="[URL unfurl="true"]http://www.giulio.org"[/URL] targetNamespace="[URL unfurl="true"]http://www.giulio.org"[/URL] elementFormDefault="qualified">
<xs:import namespace="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema"[/URL] schemaLocation="[URL unfurl="true"]http://www.w3.org/2001/XMLSchema.xsd"/>[/URL]
<xs:complexType name="elementType">
<xs:complexContent>
<xs:extension base="xs:element">
<xs:attribute name="mioattr" type="mioattrtype"/>
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:simpleType name="mioattrtype">
<xs:restriction base="xs:string">
<xs:enumeration value="union"/>
<xs:enumeration value="disjunction"/>
<xs:enumeration value="overlap"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="element" type="elementType"/>
</xs:schema>

When i validate it, all goes well, but
when i try to use this schema to validate another schema and i try to validate it, the validator come out with problems with the previous valid schema.
Can someone help me?

Not quite understandable... Maybe try rephrase it and say it again that others might be more forthcoming?
