Bug 73903 – [V8] Multiple VMs: support <script type>with types other than JavaScript.

• Component: WebCore Misc.
• Status: RESOLVED WONTFIX

[Pavel Podivilov]

The idea is to have a generic ScriptController that evaluates script element's source code using one of its sub-controllers based on mime-type.

The attached patch illustrates one possible implementation.

With this patch, ScriptController is still a JavaScript controller with additional sub-controller, but it could be refactored into a generic controller.

This is a really horrible class name.  It's still a ScriptConroller... just of a diferent kind of script.

This would need to be conrollerForMimeType?

Again, way too generic of names.
