COMMENT:
----------------------------------------------------------------------

Thank you to Ines Robles for the GENART review.

** Section 1.2.1
   2.  If the value of the "for" attribute is "custom", then the
       <ttl:ttl> element MUST also have a "custom" attribute containing
       a DNS record type conforming with the regular expression in
       Section 3.1 of [RFC6895].  Additionally, the record type MUST be
       registered with IANA.

Does this “must be registered with IANA” mean that it has a code point in
https://www.iana.org/assignments/dns-parameters/dns-parameters.xhtml?  It would
be helpful to be explicit in the text.

“Private Use” values would not be acceptable?

** Section 1.2.1.2
   To facilitate forward compatibility with future changes to the DNS
   protocol, this document does not enumerate or restrict the DNS record
   types that can be included in the "custom" attribute of the <ttl:ttl>
   element.

Does this mean no restriction beyond requiring their registration?

** Section 3.1
   Servers SHOULD restrict the supported DNS record types in accordance
   with their own policy.  For example, a server MAY allow clients to
   specify TTL values for DS records only.

This “SHOULD” statement is confusing.  When would servers NOT restrict things
according to their own policy.  It reads like it isn’t mandatory for them to
follow their own policy.
