validation and fixed: wrongly unallowed deprels

[Stormur]

I am running the validate.py script, and I receive an error for this sentence (which, I am sorry, is very long... but so it goes with Medieval Latin):

# sent_id = 170

The problem is at token 22: we have a fixed adverbial expression, in tantum 'so much (so)', meaning that tantum depends as fixed from in, and then in bears the advmod relation with respect to propinquas (25). The validator complains:

'advmod' should be 'ADV' but it is 'ADP'

Should it not be so that fixed relations do not give an error for alleged POS/deprel mismatches of fixed heads? Because, since individual elements of fixed expressions retain their morphological analysis, but the whole expression can act differently than the single parts, there can be no restrictions.

I think I have other errors like that, but I still have to check.

Hmm, this should not be happening... The validator has the condition that fixed should not be among child relations. Will investigate.

[Stormur]

Update: I tried again, and this time the error seems to be absent. I will keep an eye for this... it is not clear if it was something else that triggered it.

[dan-zeman]

I could not replicate the error (with a fresh update of tools, the above sentence copied from here and saved as a CoNLL-U file). Only dozens of undocumented/disallowed features.

[Stormur]

The error seems indeed to be gone. Sorry for having bothered!
