specifies that "A conforming producer shall be able to produce conforming documents". This is unclear insofar as that it permits the existence of "conforming producers" capable of producing - two simple, conformant "Hello World"-documents - other, non-conformant documents. Such an application still would be a "conforming producer", since it is "able to produce conforming documents".

rephrase to read "all Office OpenXML documents produced by a conforming producer shall be conforming documents."

Proposed Disposition of DIS 29500 Comment DE-0160 (Modified: 2008-01-04) It is not the intent of DIS29500 to limit the breadth of formats that a conforming producer may produce, because this could limit future interoperability with new formats. Most applications that support document formats include support for a variety of formats, and a consuming producer that adds support for a new format in the future should not be considered a non-conforming producer as a consequence of adding such support. We also note that the conformance clause for DIS 29500 has been expanded to include the concept of conformance classes, which allows for conforming producers to support defined subsets of DIS29500. For more information, including the full text of the proposed revisions to the conformance clause, see the response to JP-0027, JP-0028, or JP-0029.
