//0.8: namespace fix when saving (::content()) xml  file with XSLT transformer
//0.8: context set up after instance type; further queries made on this context if no other specified
//0.8: using gets the document from dom object , instead dumping and using the source; this way it will affect the existing object, without creating another document
//0.8: cssq and csse - css query and css evaluate; transformer provided by Zend_Dom_Query_Css2Xpath/ZendFramework-1.10.8
