It's still a little unclear, I'm afraid. I think you're saying that
you want to say that the t element must contain a c element. If so,
you can do that in XML Schema with:
<xs:element name="t">
<xs:complexType>
<xs:sequence>
<xs:element name="c" />
</xs:sequence>
</xs:complexType>
</xs:element>
The following would both be valid (assuming that the c element
declaration means that the c element can have empty content and is
nillable):
<t><c /></t>
<t><c xsi:nil="yes" /></t>
Whereas the following would be invalid:
<t></t>
<t />
<t><d /></t>
<t><c /><c /></t>
If you want to allow the c element to repeat, you should use the
maxOccurs attribute.
Cheers,
Jeni
