Setting the type of an iq to "group_roster" is not allowed. Using your own namespaces for queries is, but you are not allowed to build your own namespaces that start with "jabber:". But your company (or you as a private person) for sure has a http address, that can be used to build namespaces. You could even use your email-adress with the "mailto:"; prefix as a namespaces. Therefore the following queries would not break any rules: <iq type='get'> <query xmlns='http://yourcompany.example.com/xmlns/limitedroster'> <limit group='A'/> </query> </iq> or: <iq type='get'> <query xmlns='mailto:[EMAIL PROTECTED]'> <limit group='A'/> </query> </iq> But you could even extend the normal query. This would make your client compatible with servers that don't implement your extension: <iq type='get'> <query xmlns='jabber:iq:roster'> <limit xmlns='http://yourcompany.example.com/xmlns/limitedroster' group='A'/> </query> </iq> Tot kijk Matthias
