It is unclear how this part of the specification, wrt. its intended use or its function, relates to other parts of the specification that also allow application-defined data to be embedded into a document (Custom XML Data Storage, Custom XML Data Storage Properties, Smart Tags, Custom Markup, Structured Document Tags). It is also unclear how producer characteristics should be handled in a processing chain of linked producers and consumers.

State intended use, relation to other parts and conformance criteria wrt. producer-chains more precisely.

Part 1, section 15.2.1

ed

Proposed Disposition of DIS 29500 Comment DE-0152 (Modified: 2008-01-04) Agreed; some additional information about the intent and use of this part would be valuable. The following changes will be made in Part 1, §15.2.1, page 137, line 6: An instance of this part type contains information about additional characteristics of the producer that generated the document, when those characteristics cannot be specified using elements defined by this Standard. [Note: The contents of this part are purely informational, and do not place any requirements on subsequent consumption of the document. They are, however, intended to provide detailed information about the capabilities of the document’s producer, allowing those capabilities to be factored in during subsequent processing. For example, an application which supports 100,000 spreadsheet columns might choose to limit its output to 10,000 columns when presented with a document whose characteristics indicate that it was produced by an application with that limitation, in order prevent the introduction of content which is unsupported by the original producer (as that application might be used in the future to process this document). This markup is provided by this specification in order to provide an interoperable way of storing this information. end note]
