After two months' experience with the draft interface, however, users
have discovered four serious omissions in the original design:
1) there is no standard way to read an XML document from an input
stream;
2) there is no way to obtain contextual information (system id, line
number, etc.) for reporting application errors;
3) there is no way to obtain external identifiers for an attribute of
type NOTATIONS or ENTITIES when more than one notation or entity
name is provided; and
4) there is no way to distinguish between recoverable and
unrecoverable errors, as required by the XML REC.
People have also rightly complained that the AttributeMap interface is
too complicated. I have put together a web page containing my
suggestions for revisions to fix these problems and generally to clean
up the SAX interface; you will find the proposed revisions at the
following URL:
http://www.microstar.com/XML/SAX/proposed-changes.html
If you are interested in SAX, either as a parser writer or as an
application writer, please take a few minutes to read through this web
page. I will look forward to receiving your comments, corrections,
and suggestions.
All the best,
David
