JSR - 184 pick method

[sambatango]

From the specification:
"The pick ray is cast in the given direction from the given location in the coordinate system of this Group."

What does it mean? should the given direction be in local coordinates of the group or should the given location? or both? Can't the location and direction refer to the world's coordinate system?
Thanks for any help

i would say both, considering the sentence.
