Has this not been common knowledge for a long time? The argument for high load/low reps has always been that it a) saves time and b) will increase your strength (vs. muscle size) more. Both of which are important factors, especially if you are doing strength training not for cosmetic but health reasons. The number of 8-12 reps to muscle failure has been promoted because a too low number of reps (too high load) seems not to induce as much hypertrophy and is bad for your joints, etc..
Your statements about Germany are not correct: Factur-X is not common in Germany at all, the German version of this standard (albeit very closely related to Factur-X) is called Zugferd and it is by no means mandatory in Germany.
Actually, most governmental agencies (which have required e-invoices for many years), only accept the pure XML files. Zugferd is a bit of an interim solution until everybody is familiar with an e-invoice visualizer. There are already many free (as in beer and source) solutions available for that. Zugferd (X-Factur) is a problematic standard, because there can be discrepancies between the PDF and the embedded file and its unclear, which is authorative. Concerning the platforms: I don't know about France, but in Germany, sending e-invoices by e-mail is explicitly permitted by the government.
Well, as they should, because they are now by far the biggest emitter with higher CO2 emissions than the EU and US combined. Even their per capita emissions have surpassed countries like Germany.
Very, very well deserved! Great software at very reasonable prices. I had the ultimate collection (or whatever the package including all IDEs is called) for 3 or 4 years and it even encourages me to try out new languages once in a while. Its an excellent offering!
