Kommentarer

XML Web services-identifiering omfattar identifiering av tillgängliga XML-webbtjänster som anges, en URL. En URL pekar vanligtvis på ett identifieringsdokument som vanligtvis har filnamnstillägget a.disco. Identifieringsdokumentet innehåller referenser till information om förekomsten av XML-webbtjänster. Dessa referenser kan referera till tjänstbeskrivningar, XSD-scheman eller andra identifieringsdokument. Den här klassen representerar en referens till ett XSD-schema.

I ett identifieringsdokument finns en referens till ett XSD-schema i ett schemaRef XML-element. schemaRef XML-elementet har ett XML-namnområde och ett ref attribut. Värdet för XML-namnområdet måste matcha konstanten Namespace . Värdet för ref attributet placeras i egenskapen Ref .
