Here's a revised list of the proposed core features for Mod??SAX.
I've added one new feature -- http://xml.org/sax/features/use-locator
-- which will explicitly request the parse to supply or not to supply
a Locator through the DocumentHandler.setDocumentLocator callback.
There are two possible advantages to including this feature:
1. If the application wants a locator, it can tell before beginning
the parse whether the parser can supply one.
2. If the application does not want a locator, the SAX parser/driver
might be able to operate more efficiently if it doesn't have to
maintain the Locator information.
What does everyone else think?
In any case, here's the revised core feature list (I've also added
extra wording to make it clear that the external DTD subset counts as
an external parameter entity):
