Rationale: Acceptable fiber materials are specified at 4.7. Current text at non-mandatory Appendix X1.1.2 gives guidance for fiber use but is not mandatory information. This proposed revision brings X.1.1.2 forward into the standard with minor revisions reflecting mandatory language. While not mandating fiber use, this revision provides guidance for fiber use in mandatory language, where fiber is used.
