The OOXML XML Schemas use xml:import incorrectly. Stylesheets contain multiple import statements, each giving the same namespace, but different schemaLocation hints. It is ambiguous whether this is legal XML Schema, but it goes against the intention of the XML Schema specification (Noah Mendelsohn), is not supported by several major validation tools (e.g. XSV, Xerces 2.9, at least some versions of Tibco Turbo, and older versions of MSXML), and is not an approach recommended by XML Schema experts (Jeni Tennison, Michael Kay).

Remedy: Build an “adapter schema” which is imported in place of the multiple existing imports, which uses xs:include directives to include all the schemas that reference the same namespace. Affects files: dml-chart.xsd, dml-chartDrawing.xsd, dml-compatibility.xsd, dml-diagramColorTransform.xsd, dml-diagramDataModel.xsd, dml-diagramDefinition.xsd, dml-diagramElementPropertySet.xsd, dml-diagramElementPropertySet.xsd, dml-diagramStyleDefinition.xsd, dml-diagramStyleDefinition.xsd, dml-diagramStyleDefinition.xsd, dml-diagramStyleDefinition.xsd, dml-diagramStyleDefinition.xsd, dml-diagramStyleDefinition.xsd, dml-diagramStyleDefinition.xsd, dml-diagramStyleDefinition.xsd, dml-lockedCanvas.xsd, dml-picture.xsd, dml-spreadsheetDrawing.xsd, dml-spreadsheetDrawing.xsd, dml-spreadsheetDrawing.xsd, dml-spreadsheetDrawing.xsd, dml-spreadsheetDrawing.xsd, dml-wordprocessingDrawing.xsd, pml-animationInfo.xsd, pml-comments.xsd, pml-embedding.xsd, pml-presentation.xsd, pml-presentation.xsd, pml-presentation.xsd, pml-presentationProperties.xsd, pml-slide.xsd, pml-viewProperties.xsd

Incorrect use of xml:import

Proposed Disposition of DIS 29500 Comment GB-0621 (Modified: 2007-11-15) Agreed. Currently some of the W3C XML schema files for part 4 make use of the xsd:import functionality to import additional XSD files that all combine to define one namespace. There are multiple import statements pointing to the different locations for each XSD file. There is some ambiguity as to whether or not this method is appropriate, and many XML parsers do not support it. As a result, many of the schema files from part 4 will not work in these parsers. We will modify the schemas that use this inclusion feature in order to enable this standard’s XML schema files to be handled by Xerces-J and MSV, at least. It is possible to modify the schema files without impacting the document instances validated by the current version of the schemas. The following schema files will be combined to form one schema file, dml-main.xsd: dml-audioVideo.xsd dml-baseStylesheet.xsd dml-baseTypes.xsd dml-documentProperties.xsd dml-graphicalObject.xsd dml-graphicalObjectAnimation.xsd dml-graphicalObjectFormat.xsd dml-gvml.xsd dml-shape3DCamera.xsd dml-shape3DLighting.xsd dml-shape3DScene.xsd dml-shape3DScenePlane.xsd dml-shape3DStyles.xsd dml-shapeEffects.xsd dml-shapeGeometry.xsd dml-shapeLineProperties.xsd dml-shapeMiscellaneous.xsd dml-shapeStyle.xsd dml-styleDefaults.xsd dml-table.xsd dml-tableStyle.xsd dml-text.xsd dml-textBullet.xsd dml-textCharacter.xsd dml-textParagraph.xsd dml-textRun.xsd The following schema files will be combined to form one schema file, dml-diagram.xsd: dml-diagramColorTransform.xsd dml-diagramDataModel.xsd dml-diagramDefinition.xsd dml-diagramElementPropertySet.xsd dml-diagramLayoutVariables.xsd dml-diagramStyleDefinition.xsd dml-diagramTypes.xsd The following schema files will be combined to form one schema file, pml.xsd file: pml-animationInfo.xsd pml-baseTypes.xsd pml-comments.xsd pml-embedding.xsd pml-presentation.xsd pml-presentationProperties.xsd pml-slide.xsd pml-slideSynchronizationData.xsd pml-userDefinedTags.xsd pml-viewProperties.xsd The following schema files will be combined to form one schema file, sml.xsd: sml-autoFilter.xsd sml-baseTypes.xsd sml-calculationChain.xsd sml-comments.xsd sml-customXmlMappings.xsd sml-externalConnection.xsd sml-pivotTable.xsd sml-pivotTableshared.xsd sml-queryTable.xsd sml-sharedStringTable.xsd sml-sharedWorkbookRevisions.xsd sml-sharedWorkbookUserNames.xsd sml-sheet.xsd sml-sheetMetadata.xsd sml-singleCellTable.xsd sml-styles.xsd sml-supplementaryWorkbooks.xsd sml-table.xsd sml-volatibleDependencies.xsd sml-workbook.xsd In addition to this, Part 4, Annex F will be changed, as follows: This clause is informative.
