Schema type information provided by IXmlSerializable is invalid: Type 'string' is not declared

I've added the System.Xml.Serialization.XmlSchemaProvider attribute to my 
class to customize the schema. Some of the datatypes in my schema are 
strings, but I'm getting an error that string type is not declared.  Can 
anyone show me how to do this properly?  I've included the code to my schema 
below:

[System.Xml.Serialization.XmlSchemaProvider("MySchema")]
public class AnyTextData2 : AnyTextData, 
System.Xml.Serialization.IXmlSerializable
{
    public AnyTextData2()
    {
    }

    public static System.Xml.XmlQualifiedName 
MySchema(System.Xml.Schema.XmlSchemaSet xs)
    {
        System.Xml.Serialization.XmlSerializer schemaSerializer =
            new 
System.Xml.Serialization.XmlSerializer(typeof(System.Xml.Schema.XmlSchema));
        System.Xml.Schema.XmlSchema s = AnyTextData2.Schema;
        xs.XmlResolver = new System.Xml.XmlUrlResolver();
        xs.Add(s);
        return new System.Xml.XmlQualifiedName("AnyTextData2");//, ns);
    }
    private static System.Xml.Schema.XmlSchema Schema
    {
        get
        {
            /*
            <s:complexType name="AnyTextData2">
            <s:simpleContent>
            <s:extension base="s:string">
            <s:attribute name="Attribute" type="s:string" />
            </s:extension>
            </s:simpleContent>
            </s:complexType>
            */
            System.Xml.Schema.XmlSchema pSchema = new 
System.Xml.Schema.XmlSchema();
            pSchema.ElementFormDefault = 
System.Xml.Schema.XmlSchemaForm.Qualified;

            //<s:complexType name="CData">
            System.Xml.Schema.XmlSchemaComplexType pComplexType = new 
System.Xml.Schema.XmlSchemaComplexType();
            pComplexType.Name = "AnyTextData2";

            //<xs:simpleContent>
            System.Xml.Schema.XmlSchemaSimpleContent pSimpleContent = new 
System.Xml.Schema.XmlSchemaSimpleContent();

            //<s:extension base="s:string">
            System.Xml.Schema.XmlSchemaSimpleContentExtension pExtension = 
new System.Xml.Schema.XmlSchemaSimpleContentExtension();
            pExtension.BaseTypeName = new 
System.Xml.XmlQualifiedName("string");//"s:string"

            //<s:attribute name="Attribute" type="s:string" />
            System.Xml.Schema.XmlSchemaAttribute pAttribute = new 
System.Xml.Schema.XmlSchemaAttribute();
            pAttribute.Name = "Attribute";
            pAttribute.SchemaTypeName = new 
System.Xml.XmlQualifiedName("string");//"s:string"
            pExtension.Attributes.Add(pAttribute);

            pSimpleContent.Content = pExtension;

            pComplexType.ContentModel = pSimpleContent;

            pSchema.Items.Add(pComplexType);
            return pSchema;
        }
    }

}

Jeremy, "qualified" means "qualified with a namespace". You have no 
namespace. The name {no namespace}:string is not defined.

You need to qualifiy these names with the "http://www.w3.org/2001/XMLSchema" 
namespace.
