At global scope, right?
The "const" version cannot be changed to point to a separate
CFStringRef; the compiler prohibits you from writing:
kStringRef1 = CFSTR("another string"); // <-- illegal
The "static" version, unlike the "const" version, is not given global
linkage. It cannot be referenced from another file via extern, like so:
extern const CFStringRef sStringRef1; // <-- illegal
You can combine these properties to create a CFStringRef which cannot
be changed and does not have global linkage:
static const CFStringRef k_stringRef3 = CFSTR("local and unchanging
string");
In function scope, the meaning of "const" is the same, and "static"
is a little different. You can look it up in any C++ reference book
for details :)

Is there any difference? Is there any difference if they are used
once or more than once in the file?
Curious...
