SDTMIG v3.1.1 has it as "Inclusion/Exclusion Exceptions" (section 6.3.2, pg. 70). That's perhaps the reason you are seeing that variation.
At any rate, is there a definitive, referenceable source for dataset labels? For example, in SDTMIG v3.1.2, for LB, it is "Laboratory Test Results" in section 2.5, but "Labs" in section 6.3.3, under the section title. Throughout the IG, it seems to only emphasize on variable label, not dataset label.
In the grand scheme of things, a (slightly) different dataset label will unlikely hinder the review process. Consistency (across studies) is more important.
Anthony is right. "I/E Exceptions" label is SDTM 3.1.1 legacy issue, which should be fixed for OpenCDISC 3.1.2 specs.
Currently there are no OpenCDISC checks on datasets labels for the reasons Anthony already provided. Do you think we need to introduce them?
Anthony/Sergiy,
After some external discussions, it seems that the dataset label is not of significance, that is, if the synonymy is in align with the domains purpose. Overall, it's most likely that standard domains will have controlled terminology applied to them.
Thanks again!
There is no concept of dataset or domain labels in the latest SDTM IG. It has only "descriptions" of domain, which are not consistent across the document to use them as a source for a dataset label validation.
