+  How Properties of Mime Types are used by SQL Mode
+  =================================================
+
+  keywords:
+    A list of keywords you want to be highlighted.
+  builtin:
+    A list of builtin types you want to be highlighted (if you want types to be of class "builtin" instead of "keyword").
+  operatorChars:
+    All characters that must be handled as operators.
+  client:
+    Commands parsed and executed by the client (not the server).
+  support:
+    A list of supported syntaxes which are not common, but are supported by more than 1 DBMS.
+    * ODBCdotTable: .tableName
+    * zerolessFloat: .1
+    * doubleQuote
+    * nCharCast: N'string'
+    * charsetCast: _utf8'string'
+    * commentHash: use # char for comments
+    * commentSlashSlash: use // for comments
+    * commentSpaceRequired: require a space after -- for comments
+  atoms:
+    Keywords that must be highlighted as atoms,. Some DBMS's support more atoms than others:
+    UNKNOWN, INFINITY, UNDERFLOW, NaN...
+  dateSQL:
+    Used for date/time SQL standard syntax, because not all DBMS's support same temporal types.
