*All* aspects of source choosing are left UA-defined intentionally, so
they can make the best choice based on whatever information and
heuristics they choose to adopt.  The spec just defines how to extract
the information from the elements, and when to perform the first
choosing/loading.

Which source the UA chooses is intended to be a
quality-of-implementation issue.  It's assumed that they'll make
reasonable choices at first, and anything else is gravy.  If a UA is
making bad choices, it's intended to be dealt with by just filing a
bug against them.
