mellemFV

Could you clarify what "mellemFV" refers to? I’m not sure which domain it belongs to (for example, technology, mathematics, Danish policy or culture, a software project, or a fictional concept). With a bit more context, I can produce a concise, neutral wiki-style article (under 300 words). If you’d like, I can also draft a neutral stub as a fictional or generic concept until you provide the intended meaning.
