Thanks for this bug report and example XMP. The problem is that there is no pre-defined XMP-iptcCore:DateCreated tag, so ExifTool cannot write (or delete) this tag. The IPTC4XMPCore specification states that this tag should be in the photoshop namespace, not the Iptc4xmpCore namespace. So whatever software generated this XMP is in error. If you really have a need to delete this tag, you can create a user-defined tag in the XMP::IptcCore table to do this. - Phil
