How can i write in XSD such that it can validate the following XML:

If company element has text value = A, attributes of Price can take
USD and AUD only
If company element has text value = B, attributes of Price can take
USD and RMB only

<Company>A</Company>
<Prices>
<Price Currency="USD">12</Price>
<Price Currency="AUD">12</Price>
</Prices>

<Company>B</Company>
<Prices>
<Price Currency="USD">12</Price>
<Price Currency="RMB">12</Price>
</Prices>

I don't believe XML Schemas can express that constraint. Implement it in
application code.
