+
+   Occupancy Limit:   This attribute indicates the maximum amount of
+      time, in Time Units (TUs), that a point coordinator MAY control
+      the usage of the wireless medium without relinquishing control for
+      long enough to allow at least one instance of Distributed
+      Coordination Function (DCF) access to the medium.  The default
+      value of this attribute SHOULD be 100, and the maximum value
+      SHOULD be 1000.
+
+   CFP Period:   The attribute describes the number of DTIM intervals
+      between the start of Contention-Free Periods (CFPs).
+
+   CFP Maximum Duration:   The attribute describes the maximum duration
+      of the CFP in TU that MAY be generated by the Point Coordination
+      Function (PCF).
+
+   BSSID:   The WLAN Radio's base MAC address.  For WTPs that support
+      more than a single WLAN, the value of the WLAN Identifier is added
+      to the last octet of the BSSID.  Therefore, a WTP that supports 16
+      WLANs MUST have 16 MAC addresses reserved for it, and the last
+      nibble is used to represent the WLAN ID.
+
+   Beacon Period:   This attribute specifies the number of TUs that a
+      station uses for scheduling Beacon transmissions.  This value is
+      transmitted in Beacon and Probe Response frames.
+
+  Country Code:   This attribute identifies the country in which the
+      station is operating.  The first two octets of this string is the
+      two-character country code as described in document ISO/IEC 3166-
+      1.  The third octet MUST be one of the following:
+
+   1. an ASCII space character, if the regulations under which the
+      station is operating encompass all environments in the country,
+
+   2. an ASCII 'O' character, if the regulations under which the station
+      is operating are for an outdoor environment only, or

+/*   DTIM Period:   This attribute specifies the number of Beacon
+      intervals that elapses between transmission of Beacons frames
+      containing a TIM element whose DTIM Count field is 0.  This value
+      is transmitted in the DTIM Period field of Beacon frames.
