Private use is private use. Please read RFC 5646, sections 2.2.7 and
4.6.

BCP 47 offers many solutions for a situation like this:

1. private-use tags of the form "qlf"
2. private-use tags of the form "x-elfdal"
3. variant subtags
4. registered 5-8 letter subtags (not used yet but possible)

If the only option that will meet your needs is an ISO 639-3 alpha-3
code element, then your only recourse is to submit an appeal or a
revised proposal to the RA.

Keep in mind that such a subtag would be 5 to 8 letters. You have said
previously that this wouldn't work for you.
