+\section {Opentype feature Tags}
+The OpenType format defines a number of typographic features that a particular font may support.
+The following tables list the features defined in version 1.6 of the OpenType specification and
+applicable for Indic scripts.
+
+OpenType features may be applicable only to certain language scripts or specific languages, 
+or in certain writing modes. The features are split into several tables accordingly.
