"The compelling need exists for an open document-format standard that is capable of preserving the billions of documents that have been created in the preexisting binary formats,…" As stated, the need is for an open document-format standard that is capable of preserving the documents. This does not mean that the standard has to be a new XML representation of the preexisting binary formats. There is already an open document-format standard that is capable of preserving the documents, and that already has widespread use and for some time its evolution has "enjoyed the checks and balances afforded by an open standards process".
If the Summary needs a statement about the need for an OOXML standard, it should qualify if there is a need for another open document-format standard alongside existing established standards, and how the new standard will interoperate with established standards.

Proposed Disposition of DIS 29500 Comment GB-0011 (Modified: 2007-10-27) The document “Office Open XML Overview” was intended to provide some background and contextual information about OOXML for reviewers during both the Ecma adoption stage and the 5-month Ballot stage of the Fast-Track process. (Such a document is often referred to as a white paper.) As such, this document will not be included in the published standard.
