Authoratative Source Dcoumentation for Azure ARM Template Schema - powershell

Question

I am looking for the official documentation for Azure Desired State Configuration JSON schemas. Documentation and examples I find online go back quite a while and I feel the schemas I am using are not current. I am currently seeking the most current schema and a description of the fields for Microsoft.Powershell.DSC. This is the schema Visual Studio provides but I would like to have a complete understanding of each field and values they expect.
{
"name": "Microsoft.Powershell.DSC",
"type": "extensions",
"location": "[parameters('location')]",
"apiVersion": "2015-06-15",
"dependsOn": [
"[resourceId('Microsoft.Compute/virtualMachines', parameters('vm-SP1-Name'))]"
],
"tags": {
"displayName": "test"
},
"properties": {
"publisher": "Microsoft.Powershell",
"type": "DSC",
"typeHandlerVersion": "2.9",
"autoUpgradeMinorVersion": true,
"forceUpdateTag": "[parameters('testUpdateTagVersion')]",
"settings": {
"configuration": {
"url": "[concat(parameters('_artifactsLocation'), '/', variables('testArchiveFolder'), '/', variables('testArchiveFileName'))]",
"script": "test.ps1",
"function": "Main"
},
"configurationArguments": {
"nodeName": "[parameters('vm-SP1-Name')]"
}
},
"protectedSettings": {
"configurationUrlSasToken": "[parameters('_artifactsLocationSasToken')]"
}
}
}

The schema was documented in this blog. Feel free to ping me on the PowerShell slack (preferred) or twitter if you have any questions, #TravisPlunk. If I don't know, I can direct them to the right place.
