2 Explanation of symbols used
==============================
target Label of target instruction.
+
+3 Other tokens
+===============
+
+
+3.1 Declaration Semantic
+-------------------------
+
+
+ Follows Declaration token if Semantic bit is set.
+
+ Since its purpose is to link a shader with other stages of the pipeline,
+ it is valid to follow only those Declaration tokens that declare a register
+ either in INPUT or OUTPUT file.
+
+ SemanticName field contains the semantic name of the register being declared.
+ There is no default value.
+
+ SemanticIndex is an optional subscript that can be used to distinguish
+ different register declarations with the same semantic name. The default value
+ is 0.
+
+ The meanings of the individual semantic names are explained in the following
+ sections.
+
+
+3.1.1 FACE
+
+ Valid only in a fragment shader INPUT declaration.
+
+ FACE.x is negative when the primitive is back facing. FACE.x is positive
+ when the primitive is front facing.
