GML 3 Bezier


I have a question about GML 3 Bezier Curves.

I've worked with Bezier Curves for a while and now want to store my data in GML, now my question.

What are the knots in the type Bezier and why do I exactly need two of them ??

How the Values of the Knots are calculated ?

I want to store a cubic bezier curve.

thanks for your help

I believe that the encoding grammar in GML for Bezier curves is based on ISO 19107. As I am on travel, I do not have access to that document right now. When I return home I can provide the information you are requesting.
