Hi Joseph,

Since draft -07 date values may be truncated (i.e. --mmdd and ---dd)  when the
higher order components are not available, or the vCard author does not want
to disclose them.

The truncation feature was borrowed from ISO 8601:2000. Truncation is
preferable to using 0000, because the latter is a valid year number according
to ISO 8601:2004.

The date value 0000-02-14 in Portable Contacts should be mapped to --0214 in
vCard. The the year component in vCard date value 00000214 represents a known 
year, which cannot
be represented in Portable Contacts without loss of information.


Regards

Javier
