Values from this collection value can be used as OpcLabs.BaseLib.ResourceDescriptor.UrlString.
A generic string is used instead of System.Uri, because in some cases, the value may not represent a real URI.
The value of DiscoveryUriString is derived from this property. If you know that your discovery query returns just one discovery URI for each application element, it is easier to use the DiscoveryUriString property.
