Update to Cross-Court definition.

Remove the cross-court definition from Section 3

Because the definition of Cross-Court utilizes the definition of Court, the definition of Cross-Court implies the adjacent Court rather than the path of the ball. To clarify, the following is offered:

3.A.5. Cross-Court – A ball struck such that it's trajectory crosses the Centerline of the Court, including the imaginary extension of the centerline through the Non-volley Zones.The court diagonally opposite of the court from which the ball was last struck.

Editor's note: The terms 'Cross-Court' and 'Cross Court' are not referenced in the rulebook except in Definitions. We might want to consider simply dropping this definition.

3.A.4. Court – The area inside the outer dimensions of the baselines and sideline.
3.A.5. Cross-Court – The court diagonally opposite of the court from which the ball was last struck.

Clarification.

Any rule (such as Serve) or teaching/ coaching discussion, where the term "cross-court" is used. Truthfully, everyone who plays the game knows what cross-court actually means, but the rule book written definition is not congruent with that understanding.
