  <xs:annotation>
    <xs:appinfo>SFRotation is an axis-angle 4-tuple, indicating X-Y-Z direction axis plus angle orientation about that axis. The first three values specify a normalized axis vector about which the rotation takes place, so the first three values shall be within the range [-1..+1] in order to represent a normalized unit vector. The fourth value specifies the amount of right-handed rotation about that axis in radians.</xs:appinfo>
