Subject: [OASIS Issue Tracker] Commented: (OFFICE-3026) Public Comment: Part1 3.10.2 <config:config-item-set> too loose
[ http://tools.oasis-open.org/issues/browse/OFFICE-3026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=22040#action_22040 ]
Robert Weir commented on OFFICE-3026:
--------------------------------------
"The application settings in the <office:settings> element of of any class of OpenDocument Document (section 2.1) shall be consistent with the semantics explicitly defined for any element or attribute by this specification."
The problem is that the semantics of application settings are not specified. They are not even implementation-defined. So there is nothing written that defines them. So at the markup level, in the document, they have no semantics. There is nothing you can point to that can say whether a given string in a config-item is or is not "consistent with the semantics explicitly defined for any element or attribute by this specification".
Semantics (= behavior) is only defined once you have an ODF Consumer actually doing something. Then and only then you can speak about whether the Consumer contradicts existing defined semantics.
For example: I add a config setting to a document. In App A it does nothing. In App B it contradicts semantics defined in ODF 1.2. Is the document conforming? Only conforming when loaded in App A? Would you agree that it is odd to speak about a document whose conformance depends on the undocumented behaviors of which particular app you load it into? You see the trouble you get into? The problem is not in the document or in the App that writes the document. The problem is in the Consumer, the app that has special behaviors based on the application setting. That is why you need to formulate this as a restriction on a Consumer.

> The text describing the usage of config-item-sets has changed from ODF 1.1 to ODF 1.2 . It used to give examples of data to store in the config-item-sets, but these examples have been removed.
> Problem:
> In ODF 1.1 it was clear that the <config-item-set>-element was intended to be used to store application specific information such as zoom level and printer settings. So the element should be used to store settings that did not impact document layout nor document functionality. I would imagine that the reason for this element was to allow applications to store their individual settings as printer choice etc in the document - while still making sure that interoperability was not hurt (since these settings did not affect the document itself).
> However - this intention has somewhat failed, since not all vendors use this element exclusively for this purpose and several strategies for extending ODF has since emerged
> An example of "improper" extension of ODF (usage of <config-item-set>-element):
> OpenOffice.org stores a large number of settings that directly affect the document layout. These settings include (but are not limited to) "UseFormerLineSpacing", "AddParaTableSpacingAtStart",
> "IsKernAsianPunctuation", "CharacterCompressionType" etc. This is not the intended usage of the <config-item-set>-element since it directly affects the content of the document.
> An example of "proper" extension of ODF (usage of ODF extension mechanisms):
> Gnumeric defines a list of extensions to (primarily) ODF spreadsheets using the extension mechanisms of ODF. These include (but are not limited to) "gnm:GnmVAlign", "gnm:diagonal-bl-tr-line-style", "gnm:format-magic" etc. These are extensions to the functionality of ODF documents and they correctly use the extension mechanisms of ODF to do so.
> Further, ODF 1.2 introduces the notion of "extended documents" and this makes it even more important to be able to distinguish between documents that are extended and those that are not.
> Proposed solution:
> I propose to add the following to the specification:
> To 3.10.2 <config:config-item-set>:
> Add the following text:
> "The setting elements SHALL not contain settings that directly impact document functionality and SHALL not contain settings that impact document layout. Application settings that impact document functionality or impact document layout SHALL use the machanisms described in 21
> "Document Processing".
> Alternatively, add normatory, explanatory text to section 22.3.2 "OpenDocument Extended producers" clearly saying that any application using the <config:config-item-set>-element to store settings that affect document layout or functionality SHALL be labelled as an "Extended producer".
> Alternatively, add normatory, explanatory text to section 22.2.2 and 22.3.2:
> Documents using config-item-sets SHALL be of conformance class "OpenDocument extended documents" and Applications creating documents using config-item-sets SHALL be of conformance class "OpenDocument extended producers".
