Constant Summary

SKIPPED_ELEMENTS_PARSING =

The lists of elements skipped during parsing and comment processing need to differ. Currently there are two reasons:

* When parsing, we want to skip <yconst>, because it's just a useless
  wrapper. But when processing comments we don't want to skip it,
  because this is the element to which comments are attached to for
  various literals.

* When parsing, we don't want to skip <element>, because we need to
  handle it specially in case it's inside <map>. But when processing
  comments it's just a useless wrapper.
