New Post: Deployment schema is not updated

I've started understanding the BTDF concepts and just noticed, the structure should comply to the Deploymentframework defined in DeploymentFrameworkForBizTalk5.0.xsd.

when we create the Deployment.btdfproj, the first node which creates is
Project\PropertyGroup\Configuration

Here the xml element 'configuration' is not defined in the schema DeploymentFrameworkForBizTalk5.0.xsd and also not in the reference schema Microsoft.Build.Core.xsd.

i'm just wondering why is this mismatch between the schema and the generated xml (*.btdfproj)

can any one please help me in understanding this,

Thanks,
Manjunath, P
