Is there short date supported besides xsd:dateTime

[yasenstar]

Hello,

I want to use data property to store one Date information in my ontology, from the built-in data type, I can only choose xsd:dateTime, and I see the validation should be format like "2023-09-23T00:00:00", however, the detail Time portion is not relavent for the information collected.

Is there possible to customize one shortDate type that allow just "2023-09-23" input?

I'm using Protege 5.6.2 now, thanks.
