Hi,

I've got this xsd schema :

1/ info.xsd :

<?xml version="1.0" encoding="utf8" ?>
<xsd:schema xmlns=""
             xmlns:xsd="http://www.w3.org/2001/XMLSchema"

	<xsd:element name="description" type="xsd:string"/>

  <xsd:element name="services-test" type="xsd:string"/>
		
		<!-- definition du noeud racine 'services-test' -->
		<xsd:complexType name="services-test">
     		<xsd:sequence>
       			<xsd:element maxOccurs="unbounded" minOccurs="0" name="mat"

	</xsd:complexType>

</xsd:schema>

2/ This info.xml file :

<?xml version="1.0" encoding="utf8"?>
<services-test>
   <mat name="MAN">
     <description>mat</description>
     <contrats>
       <contrat name="CONTRAT_MAN_top2">
         <description>contrat CONTRAT_MAN_top2</description>
         <etatContrat>
           <etat name=":etatContrat:stabilise">
             <description>Stabilisé</description>
           </etat>
         </etatContrat>
         <services>
             <service name="RestitutionNomenclatureInterface"
 
wsdl="http://192.168.31.32:1511/mannaf_CA2_Z2/services/MAN/contrat_naf">
 
accessPoint="http://192.168.31.32:1511/mannaf_CA2_Z2/services/MAN/contrat_naf">
               <description>Description</description>
             </service>
             <service name="RestitutionActivitesInterface"
 
wsdl="http://192.168.31.32:1511/mannaf_CA2_Z2/services/MAN/contrat_naf"
 
accessPoint="http://192.168.31.32:1511/mannaf_CA2_Z2/services/MAN/contrat_naf">
               <description>Description</description>
             </service>
         </services>
       </contrat>
     </contrats>
   </mat>
</services-test>

3/ When I try to validate info.xml againt info.xsd, I've got this error :

xmllint --noout --schema ./info.xsd ./info.xml
./info.xml:1: element services-test: Schemas validity error : Element 
'services-test': No matching global declaration available.
./info.xml fails to validate

What do I miss ?

Thanks in advance.
