I am trying to understand the specification for curves (ties and slurs).

A slur continue defines a point with default/relative/x/y as well as two bezier points with bezier/x/y/offset/2.

So does the curve continue define a single point through which the curve passes as well as two bezier handles?

Also, why do we need both bezier-x as well as bezier-offset? Why two fields for controlling the x positioning?

Do others find the bezier attributeGroup documentation sufficient or could it be better?

Thanks.
