Support for accessing HTML template's holes dynamically #201

As per WebSharper 3 documentation examples one could access holes dynamically by passing the hole name as a string:

HTML Template

  <section class="main" data-hole="content"></section>

F# Code

type Article =
        Title : string
        Content : list<Element>

let ArticleTemplate =
            .With("title", fun x -> x.Title)
            .With("content", fun x -> x.Content)

I cannot seem to find a way to do this with the new type provider. Currently I face a scenario, as described in my stackoverflow post, where I need to populate a content hole without knowing its name at compile time. Unless I am missing something, I feel the current implementation does not cover my case.

Would it be possible to add the ability to access holes dynamically even from type-provider-managed template instances?

Yes, this makes sense and should be useful.

I have a preliminary implementation of .With(name, value) for the type provider that I'll push soon. We may also want to have a type that is not provided, so that you can load fully dynamic templates; although it should basically be equivalent to Template<"<div>">.

This is now implemented (for the server side) and released as v4.5.5. I will open a separate issue for the client side version.
