Error when trying to add type="xs:string" in XSD

Question

I am getting this error whenever I try to add the type for goal as "xs: string". I am not sure what the issue is. If I remove the type the XSD is valid, I need it to have the string type, however, when I add it I get the following error:

cvc-type.3.1.1: Element 'goal' is a simple type, so it cannot have attributes, excepting those whose namespace name is identical to 'http://www.w3.org/2001/XMLSchema-instance' and whose [local name] is one of 'type', 'nil', 'schemaLocation' or 'noNamespaceSchemaLocation'. However, the attribute, 'type' was found.

Is there another way I can still add the type "xs:string"?

   <xs:complexType>
                  <xs:sequence>
                    <xs:element  name="goal" type="xs:string" maxOccurs="unbounded">
                    </xs:element>
                  </xs:sequence>

Joseph, thanks for the entire XSD file. I validated it with Saxon 9.8.0.12 And it seems ok. Saxon says that the XSD is valid XML Schema. — Yitzhak Khabinsky, Oct 21 '20 at 21:55
Joseph, I also generated XML file based on the XSD. And validated that XML against the XSD without any problem. — Yitzhak Khabinsky, Oct 21 '20 at 22:00
Where exactly you are getting the errors? Any editor? Any web site? — Yitzhak Khabinsky, Oct 21 '20 at 22:01

According to the Saxon schema processor, your schema is correct, and the instance is valid. I don't see anything wrong with it at all.

What schema processor are you using?
