Summary0009211: AMLLib nodeset uses alias in an Extension Object and fails to load
Description

The .Net OPC SDK as of version 1.4.372.56 now fails on invalid nodeIds. This causes Opc.Ua.Export.UANodeSet.Import to fail with a SystemArgument exception, where before an effective nodeid of "ns=0;s=String" was used.
The OPC specification (Part 6 Annex F) can be read as allowing aliases only in specific locations, which would mean that the AMLLibs nodeset is invalid.
Per discussion with Randy Armstrong the specification should clarify that aliases can only be used in specific places (like referencetype ids, parent ids etc.). The AMLLibs nodeset will need to be updated.
