Build the identifier attribute descriptor

Type Parameters:

X - The type of the owner

Y - The attribute type

Parameters:

ownerType - The descriptor of the attribute owner (aka declarer).

property - The Hibernate property descriptor for the identifier attribute

Returns:

The built attribute descriptor

buildVersionAttribute
