Persistent connections and caching tilt the balance the other way since
you are reduced to only one extra GET RTT and get object re-use of the
stylsheet from then on. Putting it into each document individually
results in paying the byte overhead on *every* document (a lose for more
than a very small number documents over a single GET RTT) and loses the
most important characteristic of stylesheets - their re-use in many
documents.
