Again a question regarding animation in COLLADA.

The specs say INTERPOLATION may change for each segment. As described in the Revision B the accessor of the IN_TANGENT/OUT_TANGENT for INTERPOLATION BEZIER has 2 params, X and Y.

What happens if the INTERPOLATION changes? Aside from misinterprating the semantics, the number of parameters does not match.

I assume that for interpolation methods like linear the TANGENT Value is skipped and for real tangents, the seconed parameter is ignored.

Is that right ?
