SL3 SCORM 2004 4th Edition - changes to imsmanifest.xml since SL2

Interesting discussion here that might be related to an issue of mine. I need to create a report in SuccessFactors Learning. Working with SAP, I learned that the report only works with SCORM 2004 Edition 2 or 4 courses. I've created a sample test in Storyline 360, exported to both formats, and tried uploading to SuccessFactors Learning. With both zipped files, I get a notification that, "The parser could not validate the SCORM Import file due to the following reason(s). Proceeding with the import may incompletely import the file, or the file itself may be corrupt. You may choose to continue with the import at your own risk. Error on line 2: cvc-elt.1: Cannot find the declaration of element 'manifest'." The sample test is as simple as it can be and has a results slide. I have contacted SuccessFactors for support, but because of that notification, they say the issue lies on my end. Am I doing something wrong? Matthew, your post goes a little over my head, as I've never worked with the SCORM 2004 4th Edition imsmanifest.xml 'template' before, but I can sure relate to your comment about "everyone's favourite LMS." Ha!
