>          Issue Type: Bug
>          Components: SAX
>    Affects Versions: 2.4.0

> When schema is DTD, characters() and ignorableWhitespace() called correctly.
> However, when schema is XML Schema, all whitespace reported to characters().
> A testcase has been developed, included below.
> (This is, of course, when defining an element with element content.)
