Query: A note on central limit theorems for quadratic variation in case of
  endogenous observation times   This paper is concerned with a central limit theorem for quadratic variation
when observations come as exit times from a regular grid. We discuss the
special case of a semimartingale with deterministic characteristics and finite
activity jumps in detail and illustrate technical issues in more general
situations.
