[xml] xmlSchema : key and libxml

[Jeremie Blanc-Tranchant inrialpes fr]

Hi! 
 
I have a problem to declare a key element in my schema, then, to parse it with 
libxml : it seems to not be managed!? 
 
For example I use :  
 
<xsd:key name="DSKey"> 
        <xsd:selector xpath='/SiconosModel/NSDS/DS_Definition/DS'/> 
        <xsd:field xpath='@number'/> 
</xsd:key> 
 
And a error output is : 
 
./config/xmlschema/SiconosModelSchema.xsd:61: element key: Schemas parser 
error : Schemas: unexpected element key here 
 
 
Thank in advance,
