The specialized Control Link used to provide the connection between an ordered aggregation of Expressions and the target fields of a Texture Coordinate.
The s_expr_index field is 1-based index into the ordered aggregation of Expressions, and is used to select the specific Expression that controls the value of Texture Coordinate's s field.
The t_expr_index field is 1-based index into the ordered aggregation of Expressions, and is used to select the specific Expression that controls the value of Texture Coordinate's t field.

A text description of what the Control_Link is for
index of the expression whose value controls the s field of the affected <Texture Coordinate>. If 0, the s field is not controlled.
index of the expression whose value controls the t field of the affected <Texture Coordinate>. If 0, the t field is not controlled.
