A flag emoji is represented via a character sequence -- in this 
particular case by an emoji tag sequence, as specified in UTS #51.

The representation of flag emoji via emoji tag sequences is *OUT OF 
SCOPE* for both the Unicode Standard and for ISO/IEC 10646.

If you find that hard to understand, consider another example. The 
spelling of the word "emoji" as the sequence of Unicode characters 
<0065, 006D, 006F, 006A, 0069> is also *OUT OF SCOPE* for both the 
Unicode Standard and for ISO/IEC 10646. Neither standard specifies 
English spelling rules; nor does either standard specify flag emoji 
"spelling rules".

One declares conformance to UTS #51 and declares the version of emoji 
that one's application supports -- including the RGI (recommended for 
general interchange) list of emoji one has input and display support 
for. If the declaration states support for the flags of England, 
Scotland, and Wales, then one must do so via the specified emoji tag 
sequences. Your interoperability derives from that.
