(a) Within the period of time agreed by the parties or determined by the arbitral tribunal, the claimant shall state the facts supporting its claim, the points at issue and the relief or remedy sought, and the respondent shall state its defenses, counterclaims, or setoffs in respect of these particulars, unless the parties have otherwise agreed as to the required elements of these statements. The parties may submit with their statements all documents they consider to be relevant or may add a reference to the documents or other evidence the party will submit.
