general removal of namespace:cell (in .obo format) or in owl: <oboInOwl:hasOBONamespace rdf:datatype="http://www.w3.org/2001/XMLSchema#string">cell</oboInOwl:hasOBONamespace>|
I assume this is intentional?

This is wrong, not sure why it didnt get picked up by qc before making its way here. (It's my stuff so I will fix it next release >.<)

This is the term
[Term]
id: CL:0000695
name: Cajal-Retzius cell
But I wouldn't let this stop a release - can be fixed later.
Same thing in
[Term]
id: CL:0002453
name: oligodendrocyte precursor cell

(I think there are a few in there, not sure where this change came about)
In general there is a whole lot of use of dce in new terms -> so I'm guessing CL hasn't enforced the check yet.
Solution would be mass fix + qc check I would think

Maybe this is because of the default property in Protege?
No need to create another issue for this. I'm already working to fix this one
