The encoding of the Welsh flag

[William_J_G Overington via Unicode]

In Unicode® Technical Standard #51 Unicode Emoji there is the encoding for the Welsh flag.

This is in the section http://www.unicode.org/reports/tr51/#Sample_Valid_Emoji_Tag_Sequences

In the Status section near the start of the document is the following.

quote

A Unicode Technical Standard (UTS) is an independent specification. Conformance to the Unicode Standard does not imply conformance to any UTS.

My questions are as follows please.

Is that encoding for the Welsh flag included

in both The Unicode Standard and ISO/IEC 10646

or is it only encoded in The Unicode Standard

or is it in neither The Unicode Standard nor ISO/IEC 10646?

Unless the answer is the first listed possibility, how does that work as regards interoperability of sending and receiving a Welsh flag on an electronic communication system?
