Please add the language code qxp (Puno Quechua Q7260479) to the list of language codes supported for monolingual text values. ISO 639-3: qxp, IETF language tag: qxp.
I temporary used the code qu-x-Q7260479 (Puno Quechua) to create Lexemes (e.g., L347032), see a list of lexemes here.
Currently, the language code qu-x-Q7260479 cannot be used to add "usage examples" (P5831) to Lexemes or Forms (e.g., L1448326). Last but not least, the language code can help to describe the value of the "native label" property for the Puno Quechua item (Q7260479).
