    XML Schema question

    Hi !
    I'm kinda beginning with XML and I've got this fairly complex schema
    (±108 KB on 9 files ... ). I need to do some restriction in it.

    The structure is something like :

    --------------------------------------------------------------------
    <xs:complexTy pe name="myElem">
    <xs:sequence>
    <xs:element name="title" type="xs:string " />
    </xs:sequence>
    </xs:complexType>
    <xs:complexTy pe name="myContain er">
    <xs:sequence>
    <xs:element name="myList" type="myElem" minOccurs="1" />
    </xs:sequence>
    </xs:complexType>
    <xs:complexTy pe name="myObj">
    <xs:sequence>
    <xs:element name="myContain erList" type="myContain er"
    minOccurs="1" />
    </xs:sequence>
    </xs:complexType>
    <xs:element name="myBase">
    <xs:complexType >
    <xs:sequence>
    <xs:element name="myObjList " type="myObj" minOccurs="1" />
    </xs:sequence>
    </xs:complexType>
    </xs:element>
    --------------------------------------------------------------------


    Now, what I need to do is to make sure that a "myElem" element with
    a specific title is present somewhere, in at least one container in
    any object from the list.

    I know I can make it appear at only one place with the <keyor
    <uniquedirectiv e, but it can be at 2-3 places.

    Any help is appreciated !

      *************** * Edit
      Sorry ... a little mistake in the XML Schema : title is an Attribute
      of myElem, not an element ...

      <xs:complexTy pe name="myElem">
      <xs:attribute name="title" type="xs:string " />
      </xs:complexType>
      <xs:complexTy pe name="myContain er">
      <xs:sequence>
      <xs:element name="myList" type="myElem" minOccurs="1" />
      </xs:sequence>
      </xs:complexType>
      <xs:complexTy pe name="myObj">
      <xs:sequence>
      <xs:element name="myContain erList" type="myContain er" minOccurs="1"/
      >
      </xs:sequence>
      </xs:complexType>
      <xs:element name="myBase">
      <xs:complexType >
      <xs:sequence>
      <xs:element name="myObjList " type="myObj" minOccurs="1" />
      </xs:sequence>
      </xs:complexType>
      </xs:element>

          I'm not exactly sure what you want, but if your XML instances are
          allowed multiple occurences of elements with a title attribute, and
          you want one of them to have specific text, while the others are
          allowed other text, then I don't think you can do that in XML Schema
          at present.

          Pete.
