The exact wording for point 6 is not critical.  The important part is to 
say that we are tracking a change in the ISO standard, as opposed to 
doing something on our own like creating a new variant.  It's probably 
not necessary to include the information about 'khk' since that is 
apparent from the data.

Do not insert an Added field in the registration form.  It is not called 
for in Figure 5 of RFC 5646, which is found within Section 3.5.  You do 
need to have this field in the proposed record, though.

For subtags whose code elements are being retired from ISO 639-3, you 
need a Deprecated field.  You will also need a Preferred-Value field 
(note capitalization), but only if there is *exactly one* subtag that is 
preferred.  For 'drh', you would use 'khk' as indicated in the ISO 639-3 
report.  'btb' is different; any one of seven other subtags might be the 
correct choice.  A subtag cannot have more than one Preferred-Value, and 
cannot have a so-called "multi-part" Preferred-Value; this is an 
iron-clad rule.  In this case, the information would have to be 
expressed as a Comments field, such as:

Comments: see beb, bum, bxp, eto, ewo, fan, mct

(The template here is region subtag 'YU'.)  This is one of the few 
situations where a Comments field should be added for a core-standards 
change.

See above.  But please hold off on Lushootseed for the moment.

Frank Bennett wrote the request to deprecate 'heploc'; my minor 
reformatting was not sufficient to claim authorship.  For changes like 
these that track the core standards, whoever translates the ISO data 
into BCP 47-compatible formats is the "author."  In this case, that's 
you.

Do not add Comments fields that simply duplicate the information in the 
Preferred-Value field.

Other than this, your sample for Darkhat looks fine.  Go ahead and send 
the others for this category.  Keep an eye out for typos and copy/paste 
errors.
