I’ve been getting a few errors lately with generating ADaM using OpenCDISC 2.0.1. The spec file is attached, as is the define.xml file. When I validate the define, I get a number of errors that I hadn’t seen before. I’m not doing anything different than before, so the solution to the problem escapes me. I know the spec file is incomplete, but that shouldn’t cause the validation errors. Also, I wiped OpenCDISC 2.0.1 clean from my computer and reinstalled, and still the same problem. I’ve attached the xml and I can send later the xls spec file that generated this.

If you could shed any light on this, that’d be great. Thanks,

Dan.
