In Xsd schema, is it possible to specify the child Xml elements in a complexType to appear in any order and maxOccurs > 1?

Question

xs:sequence specifies that the child elements must appear in a sequence. Each child element can occur from 0 to any number of times.
xs:all specifies that the child elements can appear in any order and that each child element can occur zero or one time.

Is there a way to specify child elements can appear in any order and can occur from 0 to any number of times?

Thanks.

Answer 1

You can use a choice and then put maxOccurs="unbounded" on the choice e.g.

<xs:element name="foo">
  <xsl:complexType>
    <xs:choice minOccurs="0" maxOccurs="unbounded">
      <xs:element name="child1" type="xs:int"/>
      <xs:element name="child2" type="xs:string"/>
    </xs:choice>
  </xs:complexType>
</xs:element>

that way the 'foo' element can have any number of 'child1' and 'child2' elements.
