Summary0009212: NodeSet XML Specification (Annex F) should clarify where aliases are allowed
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: Opened separate issue: https://mantis.opcfoundation.org/view.php?id=9211.

Added text to 1.05.04:

Aliases may only be used in fields defined in this Annex that have the NodeId type such as ParentNodeId (F.7) or DataType (F.8). Fields with the Variant type shall not contain Aliases.
