-# Identifier Grammar
-
-The specification defines
-[some identifiers](https://spec.matrix.org/v1.9/appendices/#identifier-grammar)
-to use the Common Namespaced Identifier Grammar. This is a common grammar
-intended for non-user-visible identifiers, with a defined mechanism for
-implementations to create new identifiers.
-
-This module documents those identifiers, allowing the Elm SDK to use them.
