Where do I find the xsd files included via import in https://schemas.microsoft.com/office/drawing/2008/diagram

Regina Henschel 346

[MS-ODRAWXML] has in appendix 5.6 http://schemas.microsoft.com/office/drawing/2008/diagram Schema a schema. However, it is not complete but wants to import

igxelementpropertyset.xsd

oartspstyle.xsd

oartdocprop.xsd

oarte2o.xsd

oarttx.xsd

orel.xsd

Where do I find these?

Hi Regina,

The imported XSD filenames referenced by MS-ODRAWXML section 5.6 are not published as standalone downloadable schema files in the Open Specifications documentation. The corresponding public schema definitions are contained in the ECMA-376 / ISO/IEC 29500 schemas listed below.

The mappings were verified by matching the namespace specified in each xsd:import statement with the corresponding schema file identified for that namespace in ISO/IEC 29500-4:2016(E).

MS-ODRAWXML imported file name	ECMA-376 schema file name	namespace	types defined
igxelementpropertyset.xsd	dml-diagram.xsd	http://schemas.openxmlformats.org/drawingml/2006/diagram	`ST_ModelId`<br>`CT_ElemPropSet`
oartspstyle.xsd	dml-main.xsd	http://schemas.openxmlformats.org/drawingml/2006/main	`CT_StyleMatrixReference`<br>`CT_FontReference`<br>`CT_ShapeStyle`
oartdocprop.xsd	dml-main.xsd	http://schemas.openxmlformats.org/drawingml/2006/main	`AG_Locking`<br>`CT_ConnectorLocking`<br>`CT_ShapeLocking`<br>`CT_PictureLocking`<br>`CT_GroupLocking`<br>`CT_GraphicalObjectFrameLocking`<br>`CT_NonVisualDrawingProps`<br>`CT_NonVisualDrawingShapeProps`<br>`CT_NonVisualConnectorProperties`<br>`CT_NonVisualPictureProperties`<br>`CT_NonVisualGroupDrawingShapeProps`<br>`CT_NonVisualGraphicFrameProperties`
oarte2o.xsd	dml-main.xsd	http://schemas.openxmlformats.org/drawingml/2006/main	`CT_GraphicalObjectData`<br>`CT_GraphicalObject`<br>`CT_TextListStyle`<br>`ST_TextFontScalePercent`
oarttx.xsd	dml-main.xsd	http://schemas.openxmlformats.org/drawingml/2006/main	`CT_TextParagraph`<br>`ST_TextAnchoringType`<br>`ST_TextVertOverflowType`<br>`ST_TextHorzOverflowType`<br>`ST_TextVerticalType`<br>`ST_TextWrappingType`<br>`ST_TextColumnCount`<br>`CT_TextNormalAutofit`<br>`CT_TextShapeAutofit`<br>`CT_TextNoAutofit`<br>`EG_TextAutofit`<br>`CT_TextBodyProperties`<br>`CT_TextBody`
orel.xsd	shared-relationshipReference.xsd	http://schemas.openxmlformats.org/officeDocument/2006/relationships	`ST_RelationshipId`

The corresponding schema definitions are publicly available through ECMA-376 / ISO/IEC 29500 and can be located using the published namespace mappings described above: https://ecma-international.org/publications-and-standards/standards/ecma-376/.
