Question

I have to make a simple element that can be either be an integer or a date. The element I have to use is score.

I've looked at a few links but I don't really understand.

Answer 1

Use xsd:union to create new type consisting of the union of other xs:integer and xs:date:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="score">
    <xs:simpleType>
      <xs:union memberTypes="xs:integer xs:date"/>
    </xs:simpleType>
  </xs:element>
</xs:schema>
