This definition doesn’t work, since the Standard, in defining compliance in Section 2, says that "compliance is purely syntactic". So no behaviors are required. Therefore, by this definition, all behaviors are unspecified Surely this is not what is meant. Are these two different definitions Or two clause of which either will define the term Or both together define the term

Clarify this definition. Perhaps it is meant to say, "Behavior for which this Standard does not make a recommendation"

behavior, unspecified Office Open XML Document Part 1, Section 4

ed

Proposed Disposition of DIS 29500 Comment DE-0124 (Modified: 2008-01-04) Agreed; we will update the two definitions as follows: Office Open XML document — A package containing ZIP items as required by, and satisfying Parts 1 and 4 of, this Standard. A rendition of a data stream formatted using the wordprocessing, spreadsheet, or presentation ML and its related MLs as described in Parts 1 and 4 of this Standard. Such a document is represented as a package as described in Part 2 of this Standard . … behavior, unspecified –Behavior where this Standard imposes no requirements makes no recommendations . [Note: To add an extension, an implementer must use the extensibility mechanisms described by this Standard rather than trying to do so by giving meaning to otherwise unspecified behavior. end note]
