    [:and
      [:fn (fn [{:keys [tag]}] (= :Portfolio tag))]
      ...]
    {:tag :some-other-tag ...}))
=>
["unknown error"]

I understand that the "unknown error" is the result because malli doesn't know what to say when my custom function returns false. Can I customize this error message here?

I know I can use :enum here to do the same validation. Just want to know how to handle custom fns.

Data:

[{:key1 1 :val 4} {:key2 2 :val 5} {:key3 3 :val 6}]

I'd like to write a schema which requires all three keys key1, key2, key3 to be present in the sub maps of the input vector. How to do this?
