I have a few studies that are super old, and we use our very first version of the specs, and generate define.xml version 1.0. I’m trying to validate the define.xml using Pinnacle 21, but the errors and rejects I am seeing I have never seen while using our other validator. Things like: Missing required ‘Role’ value for ‘ItemRef’, and Missing Rank value. Does Pinnacle 21 validate Define version 1.0, or do I need to upversion to version 2.0 in order to successfully use Pinnacle 21 validator? Thanks in advance!
