template switch extending InstantiateAspectDescriptor is not called
I have created a template switch that extends InstantiateAspectDescriptor in a language that has a SimpleLanguageAspectDescriptor defined.

Hi, Wim,
Thank you for reporting. I've checked and found an important thing is missed in the doc. When you extend a concept switch, you should also add a dependency in your generator's properties saying the generator extends lang.descriptor's generator, as on the screenshot.
We'll correct the doc and add corresponding checks, I've already created an issue for that: https://youtrack.jetbrains.com/issue/MPS-28684
Thanks once again,
Mihail
Yes, that solved my issue. Thanks Mihail!
