question: public void addAttribute ( String uri , String localName , String rawName , String type , String value , boolean XSLAttribute ) throws SAXException { if ( m_elemContext . m_startTagOpen ) { ensurePrefixIsDeclared ( uri , rawName ) ; addAttributeAlways ( uri , localName , rawName , type , value , false ) ; } }
target:  Adds the given attribute to the set of attributes, and also makes sure that the needed prefix/uri mapping is declared, but only if there is a currently open element.
