Classes without an "is_a" parent throwing errors on LinkML documentation pages

[chris-grove]

There are 4 classes, at least, that have no parent classes in our LinkML model:

Identifier
IdentifiersRange
BioSampleGenomicInformation
BioSampleGenomicInformationDTO

and all of the documentation pages for these are throwing the same error:

https://alliance-genome.github.io/agr_curation_schema/Identifier/
https://alliance-genome.github.io/agr_curation_schema/IdentifiersRange/
https://alliance-genome.github.io/agr_curation_schema/BioSampleGenomicInformation/
https://alliance-genome.github.io/agr_curation_schema/BioSampleGenomicInformationDTO/

Is this because there is always expected to be some ancestral path to AuditedObject or AuditedObjectDTO (as with most classes)? Should we insist that all classes have a parent? Or maybe this is a coincidence?
