Visio 2010 XML Schema Definition Released

Visio has published the XML Schema Definition (XSD) files for the Microsoft Visio 2010 XML Drawing (.vdx) format. This schema is also known as DatadiagramML. The .XSD files allow developers to better understand the structure of Visio XML documents and design solutions that work with the .VDX file format.

The DatadiagramML Schema for Visio 2010 consists of three .XSD files:

  • visio.xsd is the core schema used by Visio 2003 and later
  • visio12.xsd is the set of extensions used by Visio 2007 and later
  • visio14.xsd is the set of extensions used by Visio 2010

More information about the schema is available in the Visio 2010 XML Schema Reference on MSDN.

Do you work directly with Visio XML files?  We’d love to hear about your scenarios in the comments.

    The xsd files does not fully match the schema definitions under Visio 2010 XML Schema Reference on MSDN.

    As an example from the schema definitions:

    Company Element (Visio XML Reference) Office 2010

    Contains user-entered information identifying the company creating the drawing or the company the drawing is being created for. Maximum length is 63 characters.

    From the xsd:

    <xsd:complexType name="Company_Type">


    <xsd:extension base="xsd:string"/>



    The maximum length specified in the Visio XML Reference is not present in the xsd

    The result is that xml files can be created that are valid but will most probably break Visio.

    Anyone care to comment ?

    What makes this XML Schema stand out among others? I think XSDForm From Ilerian Software works better than this. Take a view of its features here:
