Hey, I have a question I can’t seem to google. I was wondering if it was possible to implement some form of inheritance with schema?

For example if I have a map that represents a generic Widget I could have the schema {:id s/Str :type s/Keyword}

but if I want to have a schema for WidgetA that requires the additional keys :foo and :bar but I could also have a WidgetB that has additional keys :waz and :boo

However when defining the WidgetA and WidgetB schemas I’d love to be able to say it must be a valid Widget as well

is that possible and/or desireable?
