This is the BIML generated from an existing package. The custom properties DataType = "System.String" etc. When generating a new SSIS package from this BIML it generates a dataType = "System.System.String" and is unable to load the package. 

The fix is to remove the "System" from the BIML but this is time consuming.

Could the generation of the BIML be fixed?
