I'll clarify my point here: The mere use of the phrase "the interpretation
described in the DWARF standard" in your sentence obviously implies that
some particular interpretation exists in the standard (the grammatical
meaning of saying "the"). However, the rest of what you said makes quite
clear that no such interpretation exists in the standard. Hence, I found
this latter statement of yours confusing.

Of course I did no such thing. What I did was to suggest an interpretation
that I think actual producers and consumers should agree on, since it's
unspecified. I further meant to imply that it might be worthwhile for the
standard to actually specify this area in such detail, which it does not today.
