# --- Languages: first-class, BCP-47-tagged. English already exists as the core
#     seed gmeow:langEnglish — reused, not re-minted. Japanese has no seed, so it
#     is minted, declaring its internal private-use tag for @lang annotations.

Usage Advice

Use when

Use to declare the private-use tag (private-use-language-tag) a seed Language individual anchors — GMEOW's own internal literals carry this tag so no natural language is privileged (Principle 9), and the projection layer reconstructs standard BCP-47 from it on export (Principle 4).

Avoid when

Avoid using it on data-tier languages that never tag GMEOW's own literals (use gmeow:languageCode for registry alignment) and avoid emitting the private-use tag to consumers that require standard BCP-47 — project it through gmeow:bcp47Tag instead.

How to use

Assign one private-use-language-tag string per anchoring Language individual (functional: a single private-use tag); pair with gmeow:bcp47Tag so the projection layer can swap the internal tag for a standard one when serializing to external vocabularies.
