Subjunctive: Mood.md requires Inf and Ind, EWT writes Mood=Sub

Gist. A note in Mood.md says that the subjunctive is not recognized automatically. So the present subjunctive is annotated as an infinitive, and the past one as past indicative. EWT 2.18, however, has 57 Mood=Sub, and Tense.md itself mentions the subjunctive on VB. Some present subjunctives were left with Inf.

Guideline.

• 2.18:docs/_en/feat/Mood.md:40: «we currently also mark present subjunctive verbs as infinitives and past subjunctive verbs as past indicative verbs»;
• 2.18:docs/_en/feat/Tense.md:15: «Subjunctives with the PTB tag VB also have this feature» (Tense=Pres);
• validator registry: Mood=Sub is allowed for AUX and VERB (tools/data/feats.json, en; en/data/ud-registry-en.tsv).

EWT 2.18 data (engine; train 48, dev 3, test 6):

• VB with Mood=Sub|…|Tense=Pres|VerbForm=Fin — 49 (VERB 37, AUX 12). Lemma be — 11, then go 4, take, have, get, come 2 each. Person and number come from the subject. Example: people who are suggesting that we go out and fight them (weblog-blogspot.com_healingiraq_20040409053012_ENG_20040409_053012-0008);
• VBD were with Mood=Sub|Tense=Past — 8: If i were you (answers-20111108091921AAaLK4e_ans-0050), were I to purchase (reviews-211797-0003). EWT has not a single were with a 1st or 3rd person singular subject and Mood=Ind;
• VB with VerbForm=Inf, with its own subject, without aux and without to — 54. At least 5 of them are present subjunctives annotated as Inf:
  • encouraged that the parties reach (weblog-blogspot.com_dakbangla_20050311135387_ENG_20050311_135387-0231);
  • only fair that the FBI leak (…-0233);
  • My suggestion is that Global Counterparty use (email-enronsent41_01-0074);
  • that he bench test every part (reviews-086839-0012);
  • possible that you … mark (email-enronsent30_02-0030). The rest are pseudo-clefts (All you have to do is sign), questions without an auxiliary (Anyone know…?), I better pass.

Other 2.18 treebanks: Mood=Sub is present in GUM (27), ParTUT (18), LinES (5). In GENTLE, PUD and LittlePrince — 0.

Where the discrepancy comes from. The note in Mood.md was not updated when EWT started annotating the subjunctive. The data are not fully annotated: some present subjunctives remained Inf.
