; Value and parameter MUST match.
BIRTHPLACE-param =/ altid-param / language-param / any-param

CALSCALE can only be present when the value is a
date-and-or-time value and actually contains a date or date-time.
LANGUAGE can only be present when the value is text.
Description:
Format definition:
DEATHDATE-param = DEATHDATE-param-date / DEATHDATE-param-text
DEATHDATE-value = date-and-or-time / text
; Value and parameter MUST match.
DEATHDATE-param-date = "VALUE=date-and-or-time"
DEATHDATE-param-text = "VALUE=text" / language-param
DEATHDATE-param =/ altid-param / calscale-param / any-param
; calscale-param can only be present when DEATHDATE-value is
; date-and-or-time and actually contains a date or date-time.
Examples:
DEATHDATE:19960415
DEATHDATE:--0415

Properties registry, defined in [I-D.ietf-vcarddav-vcardrev] section
10.3.1.
+-----------+--------------+---------+------------------------+
| Namespace | Property | Status | Reference |
+-----------+--------------+---------+------------------------+
| | BIRTHPLACE | Current | RFCXXXX, section 2.1 |
| | DEATHPLACE | Current | RFCXXXX, section 2.2 |
| | DEATHDATE | Current | RFCXXXX, section 2.3 |
+-----------+--------------+---------+------------------------+
