 //		Relay Agent Options
+//			This attribute is a pointer to a large string ME whose content specifies one or more DHCP relay
+//			agent options. (R, W) (optional) (2-bytes)
+//
+//			The contents of the large string are parsed by the ONU and converted into text strings. Variable
+//			substitution is based on defined three-character groups, each of which begins with the '%'
+//			character. The string '%%' is an escape mechanism whose output is a single '%' character. When
+//			the ONU cannot perform variable substitution on a substring of the large string, it generates
+//			the specified option as an exact quotation of the provisioned substring value.
+//
+//			Provisioning of the large string is separate from the operation of setting the pointer in this
+//			attribute. It is the responsibility of the OLT to ensure that the large string contents are
+//			correct and meaningful.
+//
+//			Three-character variable definitions are as follows. The first variable in the large string must
+//			specify one of the option types. Both options for a given IP version may be present if desired,
+//			each introduced by its option identifier. Terminology is taken from clause 3.9.3 of [b-BBF
+//			TR-101].
+//
+//			%01, %18 Specifies that the following string is for option 82 sub-option 1, agent circuit-ID
+//			(IPv4) or option 18, interface-ID (IPv6). The equivalence permits the same large string to be
+//			used in both IP environments.
+//
+//			%02, %37 Specifies that the following string is for option 82 sub-option 2, relay agent remote-
+//			ID (IPv4) or option 37, relay agent remote-ID (IPv6). The equivalence permits the same large
+//			string to be used in both IP environments.
+//
+//			%SL	In [b-BBF TR-101], this is called a slot. In an ONU, this variable refers to a shelf. It
+//			would be meaningful if the ONU has multiple shelves internally or is daisy-chained to multiple
+//			equipment modules. The range of this variable is "0".. "99"
+//
+//			%SU	In TR-101, this is called a sub-slot. In fact, it represents a cardholder. The range of this
+//			variable is "0".. "99"
+//
+//			%PO	UNI port number. The range of this variable is "0".. "999"
+//
+//			%AE	ATM or Ethernet. This variable can take on the values "atm" or "eth".
+//
+//			%SV	S-VID for Ethernet UNI, or ATM virtual path identifier (VPI) for ATM UNI, as it exists on
+//			the DHCP request received upstream across the UNI. Range "0".. "4096" for S-VID; range "0"..
+//			"255" for VPI. The value "4096" indicates no S-VID tag.
+//
+//			%CV	C-VID (Q-VID) for Ethernet UNI, or ATM virtual circuit identifier (VCI) for ATM UNI, as it
+//			exists on the DHCP request received upstream across the UNI. Range "0".. "4096" for C-VID; range
+//			"0".."65535" for VCI. The value "4096" indicates no C-VID tag.
+//
+//			Spaces in the provisioned string are significant.
+//
+//			Example: if the large string were provisioned with the value
+//
+//			%01%SL/%SU/%PO:%AE/%SV.%CV<null>,
+//
+//			then the ONU would generate the following DHCP option 82 agent circuit-ID string for an Ethernet
+//			UNI that sent a DHCP request with no S tag and C tag = 3210 on shelf 2, slot 3, port 4.
+//
+//			2/3/4:eth/4096.3210
+//
+//			With the same provisioning, the ONU would generate the following DHCP option 82 agent circuit-ID
+//			string for an ATM UNI that sent a DHCP request on VPI = 123 and VCI = 4567 on shelf 2, slot 3,
+//			port 4.
+//
 //			2/3/4:atm/123.4567
