I have recently generated a couple of ListDefinitions using both SPSource and VSeWSS SharePoint Solution Generator. In both cases, surpisingly, Visual Studio reports fake schema validation errors in schema.xml like
The 'Description' attribute is not declared" for List xmlns="http://schemas.microsoft.com/sharepoint/" BaseType="0" DefaultItemOpen="0" Description=""... >...
followed by errors like
Could not find schema information for the element 'http://schemas.microsoft.com/sharepoint/:GetVar'.
Can anyone help me fix that?
