Xerces seems to disagree: it returns the entity whose start or end is
being reported.  So I guess one can't rely on it.

But it's worse: the reason I'm doing this is to determine the current
base URI, taking account of entity boundaries and xml:base.  This
seems to be impossible, since the locator returns the system ID of
the entity, not its URI.  So if there is http redirection (e.g. a
directory referred to without its trailing slash) the locator provides
the unredirected value.  As far as I can see, it's impossible to
calculate the base URI using SAX.

Are there any plans to directly support base URIs in a future version
of SAX?
