I am trying to register a SymbolAction using the following code:
context.RegisterSymbolAction(AnalyzeSymbol, SymbolKind.???);
I found the exact node I want to map using Syntax Visualizer:

You can see that the window indicates what Kindis Attribute, but the SymbolKindlisting does not offer this kind.
As you can see, I am confused - I thought that the syntax tree shows me exactly what the symbols of the symbols of the syntax nodes are talking about. But now I'm not sure.
If I am doing basically the right thing, I want to ask: where can I find out what SymbolKindenum value should be used for a given node type?
