Cannot use partial to complement parser/lexer (unless namespace is explicitly specified)

[paviad]

If you don't explicitly specify Custom Tool Namespace (-package) in the properties of the grammar project item, you cannot extend the generated parser or lexer class by using a partial class in your own source.

I think this is what C# language requires and not something this repo can resolve.

Repo can resolve by outputting an explicit namespace declaration
