I think the short answer is "there is no standard answer, different
tagging projects and tagged corpora adopt different policy on corrections
and tokenisation". For example, see
Atwell E, Demetriou G, Hughes J, Schiffrin A, Souter C, & Wilcock S. 2000.
A comparative evaluation of modern English corpus grammatical annotation
schemes. to appear in ICAME Journal, vol.24.
Even if you are using existing guidelines (you mention Penn Treebank) you
need not be bound by them if you have good reason to modify them for your
specific text genre (as long as you document your decision in your Corpus
Handbook); after all, this is what other corpus-tagging projects have
