Re: Identifying absent behavior

Hi Garrett,

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,
