U_USING_ICU_NAMESPACE is set to 0 for all the projects that rely on ICU in the
latest version of icu.gyp. So, I guess you don't need this any more.

I need this for forward declaration of icu::SimpleDateFormat. You need to say:

namespace X {
class Y;
}

You can't say:

class X::Y;

how about formatting vs stand-alone? For use in menus, stand-alone names (as
opposed to "formatting" names) are needed. We need to review the spec and add
this distinction if that's not yet covered. 

[Nebojša Ćirić, 2011/05/14 00:11:37]

We decided (last meeting) to use only standalone symbols, to avoid problems like
people concatenating symbols to get "proper" dates.
