This 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.
This value is derived from DiscoveryUriStrings. When DiscoveryUriStrings contains precisely one element, DiscoveryUriString is equal to value of this element. Otherwise, DiscoveryUriString is an empty string. Assigning a non-empty string to DiscoveryUriString clears the DiscoveryUriStrings and adds this string as a single element to the collection. Assigning an empty string to DiscoveryUriString has no effect.
Certain types of discovery queries, such as UALocalApplicationDiscoveryQuery or UALocalApplicationDiscoveryQuery with the UAApplicationDiscoveryQuery.Flat parameter set to true always return application elements which have precisely one discovery URI, and in such case it is guaranteed that DiscoveryUriString contains a non-empty string.
