I pretty much agree with your comments, and would add another bit, mainly for NANP readers. The access code for domestic long distance in Europe, and a number of other areas, is 0. This isn't part of the international number, so if you see a number like +44 (0)20 ..., the zero in parentheses should be dropped. Similarly, where a national number is referenced, the leading zero should be dropped before prepending the international access code and country code.
