> Description:
> R0042 limits supported hosted services addresses to HTTP transport
> addresses (presumably absolute). As hosted services generally share the
> network addresses (ip ddress + port) of their hosting device, allowing
> relative addresses (as done for the presentationURL field) could reduce
> the need to duplicate endpoint references for hosted services for all
> the transport addresses of their hosting device. It could also help
> simplify the management of metadata when multiple network interfaces are
> used, by allowing the hosting metadata to remain constant across network
> interfaces. This issue has appeared when a new version of the DPWS spec
> has changed hosted service addresses for logical to HTTP transport. Note
> also that there is an inconsistency in the management of metadata: the
> transport addresses of devices are not covered by the metadata version,
> while the transport addresses of hosted services are (see R2030).

> Proposed resolution:
> Allow hosted services to use relative URLs.
