Anyone know where to find the XML Schema file for Visio 2007 ?

[Geir]

Microsoft have published detailed documentation on the Visio XML Schema as part of the Visio 2007 SDK
The actual schema file (DatadiagramML.xsd) is however not part of the download.
For Visio 2003 it is available

I have searched the web widely without success

Anyone know where to find it ?

The referenced microsoft site contains detailed documentation on the schema
but does not seem to contain the actual schema file itself i.e the DatadiagramML.xsd file.

I need the actual schema file to autogenerate class libraries using xmlbeans
for manipulation and validation of Visio XML files in Java.

Anyone know where to find it ?
