WiX Standardizer can standardize not only the information in the MSI's, but also the general format of the WXS files. An example of this would be removing the Guid from all the component elements so that the default is use, or placing the feature inline with the comments instead of a feature list at the end, as well as setting the Manufacturer in one place and having it uniform throughout all MSI's in the organization. It achieves this through the use of a settings file that is either created by hand or through the included GUI.
