+
+=======================================
+I. Grammar / Syntax
+=======================================
+
+ No changes.
+
+=======================================
+II. Implementation Semantics
+=======================================
+
+------------------------------------
+II.A : Storage and Retrieval of Data
+------------------------------------
+
+ No changes.

+
+The SRB2 engine only supports the following namespace:
+ "srb2"
+
+The engine is allowed to refuse maps with an unsupported namespace,
+or emit a warning.
+
+=======================================
+III. Standardized Fields
+=======================================
+
+The SRB2 engine ignores any user-defined fields.
+All boolean fields default to false unless mentioned otherwise.
+
+Sonic Robo Blast 2 defines the following standardized fields:
