Section 4.2 says:

Original Text
-------------
IALocator-Options:  Options associated with this SRv6 Locator.  A
         variable-length field (determined by subtracting the length of
         SRv6-Locator from Option-Len minus 12).  The status code
         NoSRv6LocatorAvail indicates the server has no locators available
         to assign to the IA_SRV6_LOCATOR(s).

Corrected Text
--------------
IALocator-Options:  Options associated with this SRv6 Locator.  A
         variable-length field (determined by subtracting the length of
         SRv6-Locator from Option-Len minus 16).  The status code
         NoSRv6LocatorAvail indicates the server has no locators available
         to assign to the IA_SRV6_LOCATOR(s).

Notes
-----
Correct "12" to "16".

Section 4.2 defines: "Option-Len: 16 + the length of SRv6-Locator + the length 
of the IALocator-Options field in octets."

Therefore the length of IALocator-Options is  Option-Len − 16 − 
length(SRv6-Locator) , i.e. "Option-Len minus 16," not "Option-Len minus 12."

The erroneous "12" may have been carried over from the IA_SRV6_LOCATOR option 
in Section 4.1, whose fixed portion (IAID + T1 + T2 = 12 octets) is correctly 
"Option-Len minus 12."
