Validating xml sax parser
For example, characters are rarely checked for being in the right ranges, saving code in several locations both to make those checks and to report the associated errors.Certain syntax rules, like "--" being illegal in comments and "" being illegal in normal text, are also ignored.The bulk of the XML processors tested were non-validating ones.For applications where enforcing the rules in a document type declaration is not necessary, a wide variety of choices and design tradeoffs is available.In any case, they were definitively informed about this bug in the first week of August, and it remains unfixed at this writing. These also mask other errors that the processor should have reported.IBM's package includes several processor configurations, including validating and DOM-oriented parsers, and it works well with other XML software provided by the company. (The same symptoms exists in the validating processor, which shares the same core engine.) Thankfully, those internal errors don't show up often enough to keep this processor from correctly handling the bulk of the test suite.And the data provided as output is also not correct in all cases.||

The XML spec itself uses such constructs in its DTD, but its errata haven't yet been updated to address the issue of exactly where parameter entities get expanded and where they don't.almost three hundred were caused by this error alone.
