Do you mean I have to change the schema like that ?

<xs:element name="metadata">
  <xs:complexType>
     <xs:all>
        <xs:element name="identifier" type="xs:string"/>
        <xs:any processContents="lax"/>
      </xs:all>
   </xs:complexType>
</xs:element>

If yes, I can say that I get an error saying that the xml schema is not
valid.

Hi Yvan,
try <all> instead of <sequence>. This element allows the elements to
appear in random order but element declarations within the all =
container
cannot contain maxOccurs="unbounded" but only maxOccurs="1".
