Hi Steve,
I tried --validate and I get the same error message: [cid:[email protected]] I am using this version of Daffodil: Apache Daffodil (incubating) 2.3.0-SNAPSHOT Is that not the latest version? /Roger -----Original Message----- From: Steve Lawrence <[email protected]> Sent: Wednesday, April 17, 2019 8:29 AM To: [email protected]; Costello, Roger L. <[email protected]> Subject: [EXT] Re: I can't get the --validation flag to work The flag value is "--validate", not "--validation", I'm guessing that's the issue here. Also, is it possible you're using an older version of Daffodil? With the latest version (2.3.0), using --validation show the error message [error] Unknown option 'validation' which is a little more helpful than the older "excess arguments" error. I don't think we document anywhere the difference between on/off/limited. We should probably take Mike's description and add it the https://daffodil.apache.org/cli page - Steve On 4/17/19 6:46 AM, Costello, Roger L. wrote: > Thanks a lot Mike, that is very helpful. > > I have tried all the allowable values for the --validation flag and > none of them work.
