> Note the difference between second and third 'test' element in the document:

> Suggested fix - in SchemaValidator::normalizeWhiteSpace function last lines:
> was
> if (fCurReader->isWhitespace(*(srcPtr-1)))
> fTrailing = true;
> else
> fTrailing = false;
> now
> ...
> if (0 != *(srcPtr) && fCurReader->isWhitespace(*(srcPtr-1)))
> fTrailing = true;
> else
> fTrailing = false;
> }
> Idea: isWhitespace returns 'true' for empty string, but here 'empty string'
> does not mean whitepace.
> Please, review.
