// e. A map from SuppressMessageAttribute nodes to a boolean indicating if the attribute was used or not.

// a. If the diagnostic was suppressed with a prama, mark the closest preceeeding disable pragma
// which suppresses this ID as used/necessary. Also mark the matching restore pragma as used.
// b. Otherwise, if the diagnostic was suppressed with SuppressMessageAttribute, mark the attribute as used.

' Single --> Single
' Double --> Double
' Decimal --> Decimal
' Boolean --> Boolean
' * Date --> DateTime
' Char --> Char
' String --> String
