Commenti

L'individuazione dei servizi Web XML comporta l'individuazione dei servizi Web XML disponibili, ovvero un URL. Un URL punta in genere a un documento di individuazione, che in genere ha un'estensione di file con estensione disco. Il documento di individuazione contiene riferimenti alle informazioni sull'esistenza di servizi Web XML. Questi riferimenti possono fare riferimento a descrizioni dei servizi, schemi XSD o altri documenti di individuazione. Questa classe rappresenta un riferimento a uno schema XSD.

All'interno di un documento di individuazione, un riferimento a uno schema XSD è contenuto all'interno di un schemaRef elemento XML. L'elemento schemaRef XML ha uno spazio dei nomi XML e un ref attributo. Il valore dello spazio dei nomi XML deve corrispondere alla Namespace costante . Il valore dell'attributo ref viene inserito nella Ref proprietà .
