JSONSchema for HELM template

[UnleashSpirit]

Hi, I'm playing with json schema to write an input help for helm values and templates.
In my case, using RedHat Yaml VSCode extension (so basicaly draft07)
I'm wondering how to describe an helm value like foo: {{ .Value.bar }}
If I use "type": "string", I got an error cause it's not considered as a string, "Incorrect type. Expected "string""
If I use "type": "object", it's working, at least no error, but not pretty accurate. I can write almost everything.
Sometimes, depending on what my helm value does, I can use string and foo: "{{ .Value.bar }}" this works cause of the helm value between "
I tried string with pattern but as it's not considred as a string it fails

Any idea to define that foo: {{ .Value.bar }} in json schema type ?

The {{ }} syntax isn't valid YAML. It's a string in a YAML document that helm has special semantics for. It needs to be in quotes (foo: "{{ .Value.bar }}") to be valid YAML.

Also, what you're trying to build might already exist in https://www.schemastore.org
