Generative type provider

[MarkNicholls]

This would be great https://stackoverflow.com/questions/65465265/is-the-fsharp-data-xml-type-provider-generative-or-not/65483405#65483405

It would especially be nice to use with VB XML literals, I can use the literals to generate the output, and type providers to access the inputs.

Note: Using Type providers from a different F# assembly in a single solution, does work (subject to the provider locating the schema data (it may be in a file), and the assembly referencing FSharp.Data.
