        <para>
            <function>glBindTransformFeedback</function> binds the transform feedback object with name <parameter>id</parameter> to the current
            GL state. <parameter>id</parameter> must be a name previously returned from a call to
            <citerefentry><refentrytitle>glGenTransformFeedbacks</refentrytitle></citerefentry>. If <parameter>id</parameter> has not
            previously been bound, a new transform feedback object with name <parameter>id</parameter> and initialized with with the
            default transform state vector is created.
        </para>
        <para>
            In the initial state, a default transform feedback object is bound and treated as
            a transform feedback object with a name of zero. If the name zero is subsequently bound, the default
            transform feedback object is again bound to the GL state.
        </para>
        <para>
            While a transform feedback buffer object is bound, GL operations on the target
            to which it is bound affect the bound transform feedback object, and queries of the
            target to which a transform feedback object is bound return state from the bound
            object. When buffer objects are bound for transform feedback, they are attached to
            the currently bound transform feedback object. Buffer objects are used for trans-
            form feedback only if they are attached to the currently bound transform feedback
            object.
