Hi David,

The XMLReaderFactory is a kind of strange beast because it doesn't
use the ServiceLoader either: the specification doesn't adhere to
the ServiceLoader convention - so the class still forage for itself
inside the META-INF/services resource directory.

It may be something we will need to fix - but I'll defer to
Joe Wang in that matter.

As a general rule my personal taste would be to avoid global setters,
as these usually come with a whole lot of issues (security,
race conditions (if two pieces of code try to set different defaults),
isolation, etc...).

So if we can find a suitable solution that can leverage the
ServiceLoader mechanism that would have my preference by far :-)

best regards,
