Checklist
From Icelandic Parsed Historical Corpus (IcePaHC)
1. Does every finite (non-gapped) IP have a subject?
2. Does every CP dominate an IP?
3. Have you checked pos-tags?
a. If "það" appears, is it "ES" or "PRO"?
4. Are all argument NPs (i.e. NP-SBJ, NP-OB1, NP-OB2) dominated by IP?
5. Are all IP-level constituents of an appropriate type for the IP?
(i.e. if bare ADJP occurs at the IP level, then the main verb must be a copular verb, e.g. VERA, VERÐA, HEITA)
6. Do all traces have an associate phrase, and does every trace-associate pair have a unique index?
7. Is there some direct speech that should be tagged -SPE?
