Review Comment:
Oh, actually `<elementType>` here is a parameter so we already shows message
like you suggested as below:
```scala
case "array" =>
new ParseException(
errorClass = "INCOMPLETE_TYPE_DEFINITION.ARRAY",
messageParameters = Map("elementType" -> "<INT>"),
ctx)
case "struct" =>
new ParseException(
errorClass = "INCOMPLETE_TYPE_DEFINITION.STRUCT",
messageParameters = Map.empty,
ctx)
case "map" =>
new ParseException(
errorClass = "INCOMPLETE_TYPE_DEFINITION.MAP",
messageParameters = Map.empty,
ctx)
```
It looks confusing tho... 😅
