+
+    These are defined in `otData.py` and used to construct converters in
+    `otConverters.py`.
+
+    Attributes:
+        type: The type of the field. This string is used by `otConverters.py` to
+            select or construct the appropriate converter. It can be a simple
+            type name (e.g. 'uint16', 'Tag', 'Offset'), a specialized type (e.g.
+            'ValueRecord', 'DeltaValue'), or a more complex expression (e.g.
+            'OffsetTo(AatStateTable)', 'AATLookup(UShort)') which is evaluated
+            to create a converter factory.
+        name: The name of the field as defined in the OpenType specification.
+        repeat: If the field is an array, this defines how many times it
+            repeats. It can be an integer, or the name of another field (usually
+            a 'Count' field) that contains the number of repetitions. If it is a
+            string, it is used to lookup the count value from the table.
+        aux: Auxiliary data used by some converters. When `repeat` is not set
+            and `aux` is a string, it is often compiled into a Python
+            expression for evaluation. For repeating structs, it is often used
+            as a constant or an expression.
+        description: A human-readable description of the field's purpose.
