<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Well, I suppose you have to decide: when an English user does a
search on “date”, what’s the likelihood that the content in a
file date.h is going to be of interest to them. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<pre><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>All I’ve said all along is that the only appropriate language tag in ISO 639 for programming languages (when you have determined the content is in a programming language) is “zxx”. That refers to content such as “</span>#ifndef _DATE_H<span
style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>”, not content such as “</span>// a class for manipulating dates<span
style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>”. Deciding how Google should tag a file like date.h is an entirely different question. Absent any context, there is no right or wrong answer about how to tag *<b>as a whole</b>* a file like date.h: clearly there is about as much English content in that file as there is C (or whatever prog lang it is). In a given application context, such as how Google should tag that file as a whole, there may be good reasons to tag it one way or another. But that’s a question to be worked out in the context of that application; IMO it is not a question that should be answered in BCP 47. </span><o:p></o:p></pre>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>If you want to add text suggesting that different things may be
done in different application scenarios, including tagging programming-code
content with English comments or string literals as “en” when that provides
the attribute most useful for implementation and user experience, I have no
problem with that. But a *<b>general</b>* statement along lines such as that using
an IETF language tag/ISO 639 ID “en” for such programming code is
appropriate or that the appropriate tag for your example 9 would be “und”
is, IMO, not something that should appear in BCP 47.<o:p></o:p></span></p>
