<p class=MsoNormal>1. I think we have to be very careful here. The meaning of a
standard like ISO 639-2 is established not by <i>what we wish it would have
said, </i>nor by <i>what we would find out if we were able to read Peter's
mind.</i> It is established by the wording in the standard, and how reasonable
people could interpret it. The fact that "mis" was incorporated in
order to account for MARC codes is interesting, but is not in the text of the
standard. We can't expect users of BCP 47 to all be able to read Peter's mind
before tagging. <br>
<br>
2. When we are looking at stability, that is very important: our goal is that
once content is correctly tagged, people can depend on the fact that we will
not change the meaning of a tag out from under them. So clarifications that we
add in future versions of 4646 or the registry are fine, as long as they do not
narrow the range of reasonable interpretations. We can broaden them. So in the
case of "mis", a proposed narrowing to include just the MARC codes is
clearly disallowed, since it was nowhere stated in ISO 639-2 at the time that
"mis" was added to the language registry (the BCP 47 semantics are
established at the time we add the code). That is one of the key principles of
BCP 47, is to isolate us where necessary from instabilities in the source
standards. <br>
<br>
(The one exception we might be able to make is where something is so badly
defined that most reasonable people couldn't come up with any consistent
definition for it.)<br>
<br>
3. Now, I think there are steps that can be taken to make the above moot. I
think Peter's suggestion for ISO 639-X of broadening all of the Collections to
remove the (Other) is exactly the right strategy, and if this can be done
before 4646bis is issued, all the better. So having <o:p></o:p></p>

</ul>
<p class=MsoNormal style='margin-bottom:12.0pt'>and so on. This is useful on a
number of levels; it resolves a number of problems in the interpretation of
language codes, and makes the source standards themselves more stable. (In the
ideal case, we would have codes for each of the possible "decision
points" in the language tree. That is, if we look at any language code
such as <a href="http://www.ethnologue.com/show_lang_family.asp?code=eng">http://www.ethnologue.com/show_lang_family.asp?code=eng</a>
we'd have codes for each of the parent groupings, not just some of them, like
"Australian languages".) <br>
<br>
3. Randy raised the issue as to whether "mis" in the broad sense is
useful (as something that has linguistic content, but I don't know what it is).
It very much follows the model in #3. There are times when detection can only
determine that it looks like there is some linguistic content -- it is not just
binary data -- but current detection can't really determine what it might be.
That is, a code that means "according to our best available detection
methods this doesn't look like it is zxx". <br>
<br>
4. I'm leery of using zxx for programming languages, instead of just binary.
There is clearly some linguistic content in "if (content == null) { /*
remove the item in the lookup table */ ...}". Maybe we need another code
for this, something different than either 'art' or 'zxx'. <br>

<br>
If someone were so tempted, I would argue that would be inappropriate use of
mis. Since they do not know what it is, their declaration is that the language
identity is not determined, and the appropriate tag for that is und.
Appropriate use of mis does not require that one know the language of the
content; it does, however, require that one know it is *not* a language covered
by any of the available tags. <br>
