Randy Armstrong 2020-02-11 11:15 administrator ~0011570	The specification indicates the different subtypes can be returned depending on context. The only way to indicate this possibility in the NodeSet is to use the Structure base type as the DataType. In theory, this the NodeSet could use an abstract BaseType but this will be problematic for code generators that need to produce different code if different subtypes are allowed. At this point adding an indicator to the NodeSet which would allow the NodeSet to specify abstract supertypes would break existing tooling.
