XSD: Unable to use type defined in the same XSD

[bfejmck]

I'm writting the following XSD, however I'm having problems with it. For whatever reason, I'm not being allowed to use my simple types that I define in my XSD. I'm getting this error: \[code\]Cannot resolve the name 'mySimpleType1' to a(n) 'simpleType definition' component.\[/code\]\[code\]<?xml version="1.0" encoding="utf-8"?><xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://myNamespace" targetNamespace="http://myDifferentNamespace" elementFormDefault="qualified" attributeFormDefault="unqualified"> <xsd:simpleType name="mySimpleType1"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="http://stackoverflow.com/questions/11158423/Added"/> <xsd:enumeration value="http://stackoverflow.com/questions/11158423/Modified"/> <xsd:enumeration value="http://stackoverflow.com/questions/11158423/Deleted"/> </xsd:restriction> </xsd:simpleType> <xsd:simpleType name="mySimpleType2"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="http://stackoverflow.com/questions/11158423/foo"/> <xsd:enumeration value="http://stackoverflow.com/questions/11158423/bar"/> </xsd:restriction> </xsd:simpleType> <xsd:attributeGroup name="myAttributeGroup"> <xsd:attribute name="attribute1" type="mySimpleType1" use="optional"/> <xsd:attribute name="attribute2" type="mySimpleType2" use="optional"/> </xsd:attributeGroup></xsd:schema>\[/code\]
