Bestimmungsfront

Could you specify the intended domain for the term "Bestimmungsfront"? It is not a widely recognized standard term in major disciplines, and its meaning can vary (for example in biology, linguistics, geography, or philosophy). If you can provide the field or a bit of context, I can craft a precise, neutral wiki-style article under 300 words. If you want a generic fictional or conceptual entry, I can produce a concise stub as well.
