Binding Semantics for Varying Input/Output Data

-----------------------------------------------
114
Table 23 summarizes the valid binding semantics for varying input parameters
116
One can also use TANGENT and BINORMAL instead of TEXCOORD6 and
117
TEXCOORD7. These binding semantics map to NV_vertex_program2 input
118
attribute parameters. The two sets act as aliases to each other.
