VRML Spec.

Can someone explain the occurance of a field called nearDistance in the
PerspectiveCamera of several wrl files I have been trying to view?

The "Official" VRML 1.0 spec calls for:

OrthographicCamera {
position 0 0 1 # SFVec3f
orientation 0 0 1 0 # SFRotation
focalDistance 5 # SFFloat
height 2 # SFFloat
}

PerspectiveCamera {
position 0 0 1 # SFVec3f
orientation 0 0 1 0 # SFRotation
focalDistance 5 # SFFloat
heightAngle 0.785398 # SFFloat
}

and nowhere is there a field called nearDistance. Is this some residual from
the OpenInventor format that is not described in the VRML spec?
