Commenti

L'individuazione dei servizi Web XML comporta l'individuazione dei servizi Web disponibili in base a un URL. L'URL punta in genere a un documento di individuazione, che in genere ha un'estensione di file con estensione disco. All'interno di un documento di individuazione vengono forniti riferimenti a informazioni sull'esistenza di servizi Web XML. Questi riferimenti possono fare riferimento alle descrizioni dei servizi, agli schemi XSD (XML Schema Definition Language) o ad altri documenti di individuazione. Questa classe rappresenta un riferimento a una descrizione del servizio.

All'interno di un documento di individuazione, un riferimento a una descrizione del servizio è contenuto all'interno di un contractRef elemento XML. L'elemento contractRef XML ha due attributi: ref e docRef. L'elemento contractRef deve avere uno spazio dei nomi XML corrispondente alla Namespace costante , mentre gli ref attributi e docRef vengono inseriti nelle Ref proprietà e DocRef .
