Writeable lists?

All,

quick question as I had a discussion
regarding how to model writeable lists - before adding a JIRA entry:

- I read in wd16 / 4.1.13 writable "The
writable Facet describes only the ability of clients to modify this Object’s
value, not the ability of clients to add or remove children of this Object.
If a server does not support addition or removal of Object children through
writes, it MUST return an appropriate error response (see Section 9 for
details)."

- I don't read anything regarding "writable"
in section 6.2 Contract List

- I read in 6.8 Lists and Feeds: "Therefore,
in order to add child elements to a list which supports client addition
of list elements, servers MUST support adding list elements by writing
to the list URI with an Object of a type that matches the list’s Contract.
Servers MUST return the written resource (including any server-assigned
href) upon successful completion of the write."

In my understanding of the language
4.1.13 and 6.8 collide somehow, from 4.1.13 I understand that lists either
cannot be replaced or can only be completely replaced and from 6.8 I understand
that there is a possibility to add / remove children. My initial though
is to add a sentence to 4.1.13 to clarify writable in the list context
and to add "writable" facet to the example in section 6.8 - as
writable default is false. Was this already discussed earlier?

Mit freundlichen Grüßen / Best regards
