Valid output types for play twirl template

Question

What are the valid types that can be generated by a Twirl template in play framework? I know that I can generate HTML. I would like to generate an svg. Is that possible?

If I have a file named foo.scala.html, then I do get a generated class. foo.scala.svg does not result in a class.

Are the options documented anywhere?

I am currently using PlayFramework 2.5.2, but upgrading should be possible.

https://github.com/playframework/twirl#template-files:

Template files must be named {name}.scala.{ext} where ext can be html, js, xml, or txt.

Not out of the box. You can implement a custom format yourself though. See https://www.playframework.com/documentation/2.5.x/ScalaCustomTemplateFormat
