When doing a test map, you could get dozens or hundreds of the following error:

error btm1044: Input validation error: Could not find schema information for the element ‘http://Namespace/:ElementName.

Visual Studio Solution Explorer allows you to right-click on a .btm map and specify a property called “TestMap Input Instance”. If you specify a file that totally doesn’t match the expected schema, then you can receive the error above.
