Some comments about draft-arkko-multi6dt-failure-detection-00.txt:
 - in the intro a missing < before xref target='transport'/>
 - in 3.1 link-local IPv6 addresses, private (RFC 1918) IPv4 addresses,
   etc, are excluded. IMHO this is a too strong constraint: only
   ambiguous zone limited addresses should be excluded (note that
   one (only) address cannot be ambiguous).
 - in 3.2 s/the relevant default router/a relevant default router/
   (links in a resilient multi-homed environment should be served
    by more than one default router :-)
 - in 3.2 "Theoretically, it is also
   possible for hosts to learn about routing failures for a particular
   selected source prefix, even if no protocol exists today to
   distribute this information in a convenient manner."
   I disagree about the last part: there is a well known and simple
   protocol to announce routing failures for a source prefix: deprecate
   it, i.e., send RAs with zero preferred lifetime in the prefix info.
