Hi,

W3C XML Schema has no notion of root element, any glogal element can be the root of a document that uses that schema.

Global elements are defined as top level schema components, therefore they cannot be declared under some other element. Those are local elements.

If you want to specify the Bank element as a 1-unbounded sequence of Cutomer and Product and define these two elements as global elements in your schema then you can do it like below:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://xml.XMLCourse.edu/targetNS" xmlns="http://xml.XMLCourse.edu/targetNS">

  <xsd:element name="Bank">

    <xsd:complexType>

      <xsd:sequence minOccurs="1" maxOccurs="unbounded">

        <xsd:element ref="Customer"/>

        <xsd:element ref="Product"/>

      </xsd:sequence>

    </xsd:complexType>

  </xsd:element>

  <xsd:element name="Customer"/>

  <xsd:element name="Product"/>

</xsd:schema>
