The latest working draft of the vCard Ontology [1] is based on RFC6350 [2] which defines birthday as: "The default is a single date-and-or-time value"

We can add xsd:gYear to the range for the birthdate data property to support "year-only" birth dates.
(and possibly to the anniversary property too)
