How to eliminate the masteryscore element from imsmanifest.xml?
The question seems to have a simple answer, such as... open imsmanifest.xml and delete the XML element. However, I would like to know what publish settings control the appearance of that element in the published output, as I try to avoid any post-publish alterations of SCOs, since these steps are subject to procedural rigor (i.e. human error).
See page 2-19 of this document for information regarding the role of masteryscore on the status.
