error message when modifying XSD file

Question

I have a xsd file,in which the schema looks something like below:

<xs:complexType name="ABC" final="#all">
  <xs:sequence>
     **<xs:element name="XYZ" type="xs:string"/>**
  </xs:sequence>
</xs:complexType>

what is the issue if i want add attribute use = required to the XYZ element. I always get the following error - The 'use' attribute is not allowed.

Regards

I'd use process of elimination. Start removing the child nodes until you don't get the error anymore. Are you trying to read or write the XSD? — MacGyver
i am trying to modify the existing xsd file, to make sure that XYZ element is always specified in the xml file. — Dexter

Use the minOccurs and maxOccurs attributes on xs:element to indicate the minimum and maximum number of occurrences. The default is minOccurs="1", maxOccurs="1".

PS. It looks as if you were guessing. With XSD, guessing won't get you very far; even after years using the language, I still need a reference book by my side.
