Hi Peter,

There are some similar checks in the configuration, so while there are not immediately any plans to add this check (to my knowledge), I’ll ask the developers who work on the rules to review it and see if it’s something that we should include in future releases. Thanks for the suggestion!

Regards,

Tim

Hello,

Hi Peter,

The rule you are looking for is [SD0013: Begin day must be less than or equal to end day](http://www.opencdisc.org/projects/validator/rules/sd0013). It’s assigned to every domain that has --STDTC and --ENDTC variables.

Regards,

Hi,

I had a two part question/suggestion. I noticed there were no checks for any --STDTC being greater than --ENDTC in any domain. Is this something that will be added in a future release? I can modify the config files to add this rule in there, I just thought it might be an important rule to check, and thought it was present in the WebSDM checks.

Thanks,

Peter
