+We need a mechanism for writting to the automatic styles contained in content.xml. 
+Styles that should be placed here are styles used for particular elements, for example 
+colors of particular tables rows.
 
+Automatic styles are written before the document contents is processed, so my solution is to
+open a temp file, where commands can write style changes. This file will be then included in 
+the next pass at the correct place in the XML file.
