or-type kind argument doesn't throw error if the value is not provided

[Arpita-Jaiswal]

-- or-type kind:
-- constant integer special: 0
-- constant integer regular: 1
-- end: kind

-- foo: Hello

-- component foo:
caption title:
kind kind:

<Some implementation>

-- end: foo

The -- foo: Hello should have thrown an error since kind is not passed.
