Ok, "it doesn't have to" but should be possible. I'm not saying that
every body have to use "& apos;", but it should be doable.
In fact I can see the point on the need of using both entities here.
Let's talk about this particular case. The generated XML represents an
invoice. That invoice must be able to contain any kind of company name
or person name in the whole country.
I do consider possible to have some company that has an apostrophe in
its name (i.e: [Somebody's Store]). Also could imagine some other
company with double quotes in it's name (i.e: ["SomeInventedName"
invetions store]). Or even both (i.e: [Sombody's "GREAT" inventions]).
My point is that in this case at least, is not possible to stick to
either one of these two attribute value delimiters. As I can see, you
must use entities to generalize the "digital" invoice use.
Am I right?
