AS REPORTEDno primary record reached; this is what the reporting says

Is it true that all formal grammars can be classified as either dependency or constituency grammars?

No. Formal grammars encompass broader classifications such as the Chomsky hierarchy (regular, context-free, etc.) and transformational grammars, meaning they cannot be exclusively classified into only dependency or constituency grammars.
