## Known issues

Sentence token IDs
  Due to changes in sentence tokenization, the running ID numbers in the examples in the documentation may no longer always match the current ID numbers. If necessary, the examples can be traced back to their source via the page numbers in the IDs, which are stable.

ALL
  There likely remain inconsistencies in the annotation of ALL in its floated quantifier vs. intensifier use, both within PPCME2 and between PPCME2 and the later corpora.

AS X SAID
  The `-PRN` dash tag on AS X SAID and similar parenthetical expressions is likely appended inconsistently, especially in the later corpora.

Backwards gapping
  Backwards gapping may be mistagged as ordinary gapping.

Comparative clauses with elision
  In comparative clauses with elision, brackets around elided subordinate clauses are likely to be missing.

Departicipial adjectives
  Departicipial adjectives (INTERESTING, INTERESTED) in predicate position may be mistagged as participles (`VAG`, `VAN`), especially in the PPCME2.

Direct speech
  Direct speech fragments may be labeled `FRAG` rather than `QTP`.

Gapping and parentheticals
  In connection with gapping and parentheticals, hyphens preceding numerical indices sometimes replace expected equal signs.

Infinitival adjuncts
  Infinitival adjuncts (`IP-INF-ADT`) may be missing the `-ADT` tag.

Lemmatization
  Words that should have derived lemmas may have compound lemmas, and vice versa.

Measure phrases
  In searches for measure phrases (`NP-MSR`), it is wise to include quantifier phrases (`QP`), and vice versa.

Proper nouns
  Many inconsistencies and outright errors likely remain in connection with proper nouns (`NPR`).

  The guidelines for proper nouns of the form THE N OF NP (THE WAR OF THE ROSES) have the counterintuitive result that none of the nouns is tagged `NPR`.

Pseudo-imperatives
  Pseudo-imperatives are not annotated in the PCEEC.

Purpose infinitives
  Purpose infinitives (`IP-INF-PRP`) may be missing the `-PRP` dash tag, particularly in connection with GO and SEND.

Reduced relative clauses
  In searches for reduced relative clauses (`RRC`), it is wise to consider including ordinary participial clauses (`IP-PPL`), and vice versa.

Right node raising
  Instances of right node raising may be missing the index required by the guidelines, particularly in the statutes.

Secondary predicates
  Secondary predicates (`ADJP-SPR`, `NP-SPR`) may be mistagged as simple predicates (marked by `-PRD`) of small clauses (`IP-SMC`), and vice versa.
