I daresay that may. That doesn't change the convention. This mailing list
speaks English. If we didn't obey that convention things might get a

I think it would be unlikely that both would exist. However I would assert

The point of the . as delimiter is that each number is not a real but an

No, he's using an integer delimited with dots. You'll see this same
behaviour in the sectioning commands in LaTeX.

Consult The LaTeX Comanion Section 11.10 which comes after 11.9. Try
section numbering in MS Word, LaTeX, OpenOffice
version numbering in CVS, SVN,

No I pointed out that it was a software convention and gave an example in
unix. I don't think dir in Win32 has such a rich syntax and Microsoft
certainly don't tend to number things consistently, they do it for

His numbering scheme is consistent with both scenarios. That doesn't make
either of the above wrong.
