How do I create a schema for elements with attributes

[Christian Wikander]

How can I create a schema for the following?

<Data>
<Value unit="m/s">10</Value>
<Value unit="ºF">25</Value>
</Data>

I would like to have the following description in the xsd

<xs:complexType name="rootSchema">
xs:sequence
<xs:element name="Value" type="valueSchema" maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
<xs:element name="Multicalc" type="rootSchema" />

How do I write the definition of valueSchema? (I hope I didn't make any mistakes in the definitions. I simplified things a bit compared to my own xsd.)

see if this works

<xs:complexType name="valueSchema">
    xs:simpleContent
      <xs:extension base="xs:integer">
        <xs:attribute name="unit" type="xs:string" use="required" />
      </xs:extension>
    </xs:simpleContent>  
  </xs:complexType>
