The nature of the relationship and the content of thedpws:Relationship element are determined by this value. This value should be compared directly,as a case-sensitive string, with no attempt to make a relative URI into an absolute URI, tounescape, or to otherwise canonicalize it.dpws:Relationship/@Type = "http://docs.oasis-open.org/ws-dd/ns/dpws/2009/01/host"This is a specific, hosting relationship type to indicate the relationship between a HOSTEDSERVICE and its hosting DEVICE. This relationship type defines the following additional content:dpws:Relationship/dpws:HostThis is a section describing a hosting DEVICE. At least one of ./dpws:Host or ./dpws:HostedMUST be included.dpws:Relationship/dpws:Host/wsa:EndpointReferenceEndpoint Reference for the host, which includes the stable identifier for the host which MUST bepersisted across re-initialization (see also R0005 and R0006). If ./dpws:Host is omitted, impliedvalue is the Endpoint Reference of the DEVICE that returned this metadata in a Get ResponseSOAP ENVELOPE.dpws:Relationship/dpws:Host/dpws:TypesUnordered set of Types implemented by the host. (See [WS-Discovery].) If omitted or ./dpws:Hostis omitted, no implied value.dpws:Relationship/dpws:HostedThis is a section describing a HOSTED SERVICE. . It MUST be included by a DEVICE for eachof its HOSTED SERVICEs. It MUST be included by a HOSTED SERVICE for itself. For thehosting relationship type, if a host has more than one HOSTED SERVICE, including onerelationship that lists all HOSTED SERVICEs is equivalent to including multiple relationships thateach list some subset of the HOSTED SERVICEs.dpws:Relationship/dpws:Hosted/wsa:EndpointReferenceEndpoint References for a HOSTED SERVICE.dpws:Relationship/dpws:Hosted/dpws:TypesUnordered set of Types implemented by a HOSTED SERVICE. All implemented Types SHOULDbe included.dpws:Relationship/dpws:Hosted/dpws:ServiceIdIdentifier for a HOSTED SERVICE which MUST be persisted across re-initialization and MUSTNOT be shared across multiple Hosted elements. ServiceId MUST be unique within a DEVICE.This value should be compared directly, as a case-sensitive string, with no attempt to make arelative URI into an absolute URI, to unescape, or to otherwise canonicalize it.CORRECT:wsdd-dpws-1.1-spec-os 1 July 2009Copyright © OASIS® 2009.
