This is an excellent comment, but it may be in
the wrong place (or I may be misunderstanding).
I *think* the desc="" is to help the person
doing localization of the text. This feels more
like a note to another programmer rather than a
translator (WDYT?)

I agree with your assessment. Initially I did not think about it too much, just
copied it over from
https://code.google.com/p/chromium/codesearch#chromium/src/chrome/app/generat....
Removed the part of the comment that is not helpful for translation. Not sure if
it is worth moving the removed part elsewhere in the code. Let me know if you
have a suggestion.
