Question about CHOICE on xsd[Resolved]

I'm writing an XSD to be used for data import... (trust me this question is easy just verbose)


I have an object called Contact. Now, a Contact can be a PERSON, BUSINESS, or AGENCY REPRESENTATIVE. A Contact also contains other elements about a contact (phones, addreesses, etc)...

I would love for the XSD to be able to validate an xml file input like this...
<CONTACT>
<PERSON>...</PERSON>
<PHONENUMBER />
<CALLSMADE />
</CONTACT>

<CONTACT>
<BUSINESS />
<PHONENUMBER>
<CALLSMADE />
</CONTACT>



In this way, I can restrict the first element thats fall under the CONTACT element, to either a PERSON, BUSINESS, or AGENCY REP.

However, I can't seem to figure out how to make this restriction without inserting an intermediate container element to restrict those choices..

Using my intermediary way... I would have to have this for the XML input..
<CONTACT>
<ENTITYTYPE>
<PERSON>
</ENTITYTYPE>
<PHONES />
<CALLSMADE />
</CONTACT>

I don't think that's right, because it seems unnecessary to have to define an ENTITYTYPE just to restrict to three values...

Any help on this would be appreciated..
