• <<: Are the X values of the first bounding box strictly less than those of the second one?
• >>: Are the X values of the first bounding box strictly greater than those of the second one?
• &<: Are the X values of the first bounding box not greater than those of the second one?
• &>: Are the X values of the first bounding box not less than those of the second one?
• <<: Are the X values of the first bounding box strictly to the left of those of the second one?
• >>: Are the X values of the first bounding box strictly to the right of those of the second one?
• &<: Are the X values of the first bounding box not to the right of those of the second one?
• &>: Are the X values of the first bounding box not to the left of those of the second one?
• <<|: Are the Y values of the first bounding box strictly below of those of the second one?
• |>>: Are the Y values of the first bounding box strictly above of those of the second one?
• &<|: Are the Y values of the first bounding box not above of those of the second one?
• |&>: Are the Y values of the first bounding box not below of those of the second one?
• <</: Are the Z values of the first bounding box strictly in front of those of the second one?
• />>: Are the Z values of the first bounding box strictly back of those of the second one?
• &</: Are the Z values of the first bounding box not back of those of the second one?
• /&>: Are the Z values of the first bounding box not in front of those of the second one?
• <<#: Are the T values of the first bounding box strictly before those of the second one?
• #>>: Are the T values of the first bounding box strictly after those of the second one?
• &<#: Are the T values of the first bounding box not after those of the second one?
• #&>: Are the T values of the first bounding box not before those of the second one?

Invalid operations should throw accordingly
