Subject: Fwd: IESG expert review for the registration request "xliff+xml"

Hi all,

IESG has reviewed our provisional media type registration and requested below changes/explanations.
Given that we have only 30 days to provide the amended version, we should look into this immediately and pass a resolution in the meeting of 3rd February.

The reviewer had two types of concern

1) encoding considerations, which seems some misunderstanding that I will hopefully address with Robin

2) which seems more serious, security considerations

The reviewer is not happy with our statement that XLIFF has only standard XML security considerations.

We not only have extensibility, as the reviewer suspects but we also have a few standardized ways how to embed or reference executables, so they require a description how to address related risks externally (or internally, be we do not have any internal methods to address that IMHO and AFAIK).

I would very much appreciate if a TC member or a group of TC members who have experience with
1) media type registrations: Felix?, Jirka?
2) security handling of embedded executables: Fredrik?, Yves?, Jirka?
This is just my best guess who might be the suspects best suited to address this.. Please do not hesitate to take part even if you are not one of the listed suspects!
drafted the security considerations sections before our next meting, pretty much during this week.

Thanks for your attention

Hi David.  Please see the communication below (received today) and the 30-day expectation formulated for a response to the IESG reviewer via the ticket system.

They offer to answer questions, if necessary ("If you have any questions, please don't hesitate to contact us.")


Dear Robin,

The IESG-designated expert has reviewed this request and returned the inline comments below. Please reply to this message within 30 days of 27 January with a revised version of the security considerations section and a response to the reviewer's question about encoding considerations.

If you have any questions, please don't hesitate to contact us.

Best regards,

Amanda Baber

This implies the XML only uses charsets such as utf-8, and never utf-16. Are
you sure this is what you want? I don't see anything in the specification that
limits things to utf-8, although the examples are all in utf-8. If
utf-16 and similar charsets can be used this needs to change to binary.

This isn't close to adequate. All RFC 7303 is describe the generic security
considerations for XML; you need to document those that are specific to this
type or explain why there aren't any.

In discussing the security considerations for a media type it is
necessary to cover at least these points:

(1) State whether or not the media type contains active or executable
    content. If the media type does contain executable content explain
    what measures have been taken to insure that it can be executed
    safely, e.g. a sandbox, safe operation set, signed content, etc.

(2) State whether or not the information contained in the media type
    needs privacy or integrity services.

(3) If the answer to (2) is yes, elaborate on any privacy or integrity
    services the media type itself provides, or if it doesn't provide such
    services, explain how they should be provided externally, e.g., through
    the use of SSL/TLS.

I don't see anything about executable content in the specification, but this
needs to be written by someone who knows for sure. I also note that XML
vocabularies are sometimes extensible (I didn't see that anywhere but I could
have missed it) and if so that needs to be noted as a source of possible
executable content.

I would expect there to be content of this sort that requires privacy or
integrity protection; it may or may not be appropriate to specify how that
would be provided (e.g., externally with SSL/TLS or internally with XML
