Summary:
The specification should not contain underspecified features.
Justification:
Underspecified features and settings, such as “autoSpaceLikeWord95″, “footnoteLayoutLikeWW8″, “lineWrapLikeWord6″, “mwSmallCaps”, “optimizeForBrowser”, “shapeLayoutLikeWW8″, “supressTopSpacingWP”, “truncateFontHeightsLikeWP6″, “useWord2002TableStyleRules”, “useWord97LineBreakRules”, “useWord97LineBreakRules”, “wpJustification”, “wpSpaceWidth”, “sldSyncPr”, “securityDescriptor”, and “revisionsPassword” preclude uniform implementation and thus inhibit interoperability.
All features should be specified in enough detail to enable uniform interpretation by multiple implementations. Those that cannot be specified in sufficient detail should be removed.

Proposed Disposition of DIS 29500 Comment NO-0009 (Modified: 2008-01-08) We agree that underspecified features inhibit interoperability, and instances of this should be corrected. It is important to note that the initial draft received considerable contributions through the work of Ecma TC 45, and, as a result, grew from approximately 2,000 to 6,000 pages, which constitutes the current DIS 29500. We believe that a great deal of due diligence was performed to ensure that the contents of the spec were specified completely. Regarding the specific information requested, those details have been provided, including the following: Compatibility Settings (such as autoSpaceLikeWord95) We agree that these should have been thoroughly documented; this information is provided in the disposition to BR-0001, BR-0064, CA-0020, CA-0079, CH-0016, DE-0036, DK-0041, DK-0149, DK-0154, IE-0010, IN-0005, IN-0017, IN-0076, KR-0006, MY-0019, PT-0043, PT-0044, SG-0001, US-0002, UY-0001, VE-0008, and VE-0009. Security Descriptor We agree that the format of the security descriptor was not well defined; a complete description is provided in the disposition to BR-0043, CA-0041, CL-0201, CO-0150, DE-0091, FR-0346, GB-0299, GR-0081, KE-0060, PT-0097, US-0143, and VE-0059. Slide Sync Properties We agree that this is needed; a complete description of this mechanism is provided in the disposition to IN-0022. Passwords We agree that the password-hashing mechanism was not well defined; a complete description is provided in the disposition to BR-0042, CA-0039, CL-0199, CL-0200, CO-0142, CO-0149, DE-0090, FR-0339, FR-0344, GB-0295, GB-0297, GR-0075, GR-0080, IN-0065, IR-0046, KE-0059, PT-0092, US-0137, and US-0142. As well, during the ballot resolution phase, other National Bodies requested additional information about specific issues, which was also provided, as follows: Numbering Formats A full normative description of each numbering format was added in response to BR-0030, BR-0031, CA-0032, CL-0006, CL-0007, CL-0131, CL-0134, CO-0133, CO-0136, DE-0074, DE-0078, DK-0026, DK-0145, ECMA-0042, FR-0326, FR-0330, GB-0280, GB-0284, GR-0057, GR-0060, IN-0018, IN-0042, JP-0064, KE-0039, KE-0042, PT-0073, US-0075, US-0113, VE-0043, and VE-0047. Calendar Formats Normative definitions of each calendar supported by the DIS were provided in response to GB-0253 and US-0045. Page Borders Improved descriptions of page borders, including normative graphics in ISO 15948 format were provided in response to BR-0026, CA-0027, CL-0126, CO-0126, CZ-0029, DE-0094, DK-0023, DK-0141, ECMA-0041, FR-0321, GB-0271, IR-0032, KE-0033, PT-0066, US-0048, US-0072, VE-0030, and VE-0031.

shapeLayoutLikeWW8 issue is a dupe of CL-98, which contains more details.
also Dupe of GB 299
