   Re: [xml-dev] SAX Locator vs {start,end}Entity

This might be because SAXON uses AElfred2 by default. Dave Brownell was very
concerned with base URIs, especially in later versions of AElfred2. There is
even a warning fired when the base URI cannot be determined ("must be
absolute") So I am not sure if this would be indicative of all parsers...
one could argue that AElfred2 is generally "right" on these kinds of things
and that checking the locator on event callback is a Good Thing.
