se-Latn = Swedish written in Latin script
se-Cyrl = Swedish written in Cyrillic script
se-Maya = Swedish written in Mayan hieroglyphs

se-Zxxx = Swedish, explicitly not written

"se-Zxxx, fi-Latn" = content includes non-written Swedish plus Finnish
written in Latin script

Examples of multiple streams of content, such as video in one language
that is subtitled in another, call for multiple language tags. That is
not a shortcoming or failure of the language tag mechanism. See RFC
5646, Section 4.3.

All of this was discussed in the WG by the same parties.

I searched the ietf-languages archives and did not find any sort of post
or proposal from you. I forwarded one of your messages from SLIM to that
list in November 2015, expecting you to follow up with a proposal, but
nothing materialized.
