How to find out which UD POS tag the fine-grained tags used by the model is converted to

[BLKSerene]

Hi, the model details page of the Chinese transformer model lists INF and URL (for URLs?) in its tagset, but it only returns a warning when using spacy.explain on them:

Warning (from warnings module):
  File "D:\Python\lib\site-packages\spacy\glossary.py", line 20
    warnings.warn(Warnings.W118.format(term=term))
UserWarning: [W118] Term 'INF' not found in glossary. It may however be explained in documentation for the corpora used to train the language. Please check `nlp.meta["sources"]` for any relevant links.

nor could I find any useful information in the documentation of OntoNote 5 or the Chinese Penn Treebank.

And is there a direct or easy way to find out which UD POS tag the fine-grained tag used by the model is converted to? e.g. JJ -> ADJ
