The specification as described in part 2 contain more material than actually necessary for implementation of support for the ECMA-376 specification, according to the description in Part 1 section 9.1. This lead to some confusion, as the Part 2 of the specification covers more material, than actually is need as stated in part 1 Section 9.1
This should be resolved as it also overload the current specification with un-exposed nominative information, which lead to unnecessary work for would-be implementer.

To the extend there are elements that are necessary for implementation those shall be included as part of the normative Part 1.

Proposed Disposition of DIS 29500 Comment DK-0054 (Modified: 2008-01-04) Agreed; the Open Packaging Conventions (OPC) can be used in contexts other than DIS 29500, and OPC should be available for reference and re-use on its own. This has been addressed in the disposition to NB comments DE-0120, DK-0059 through DK-0063, KE-0003, US-0021, US-0253 and others, which proposes that DIS 29500 be made into a multi-part standard with the existing Part 2 (Open Packaging Conventions) restructured as DIS 29500-2. This will allow for re-use of OPC by other standards, which may choose to use additional features of OPC that are not used by DIS 29500. In addition to this, there are no longer any additional constraints placed upon OPC that are specific to the Open XML formats. This is handled by the proposed resolution to CA-0007, CO-0004, DE-0004, DK-0099, FR-0009, GB-0036, KE-0017, PT-0027, and US-0031.
