question: public void ignorableWhitespace ( XMLString text , Augmentations augs ) throws XNIException { try { if ( fDocumentHandler != null ) { fDocumentHandler . ignorableWhitespace ( text . ch , text . offset , text . length ) ; } if ( fContentHandler != null ) { fContentHandler . ignorableWhitespace ( text . ch , text . offset , text . length ) ; } } catch ( SAXException e ) { throw new XNIException ( e ) ; } }
target:  Ignorable whitespace. For this method to be called, the document source must have some way of determining that the text containing only whitespace characters should be considered ignorable. For example, the validator can determine if a length of whitespace characters in the document are ignorable based on the element content model.
