Discussion

Use a value of this type in place of either a CFString or a SecTransformAttribute when referring to transform attributes, such as with the attribute parameter in calls to the SecTransformCustomSetAttribute(_:_:_:_:) and SecTransformCustomGetAttribute(_:_:_:) functions. When using a name, see Transform Attributes for a list of valid key names.
