Support highlighting of embedded Groovy scripts inside XML CDATA blocks

[Tassil0]

On our project we use Groovy scripts that are embedded directly in XML CDATA blocks, this feature would be very helpful for this, since now there's no way to get syntax highlighting working in this use case.

Addition to this feature would be to somewhere specify what variables and types are available in these one-off scripts, since in my use case there are variables and methods injected at runtime which you can freely use.

Can you please provide some sample files.
Does it work in any other editor?

This works in IntelliJ IDEA, you can specify which language is injected in the XML and it will highlight accordingly. However it does not support more advanced intellisense like i specified in the second paragraph. It does have intellisense for built-in methods though, e.g. methods available for a String type.

Here's an example of such a file:
