[Inkscape-devel] missing release notes, help needed

For most missing/cryptic/inadequate descriptions I was able to get them into shape myself, but for these two sections I just don't have enough information:

http://wiki.inkscape.org/wiki/index.php/Release_notes/0.47#Document_Properti... http://wiki.inkscape.org/wiki/index.php/Release_notes/0.47#Object_Properties...

Please fill these out in detail, using full sentences, describing all aspects and controls and behavior, in a way everyone can understand. This _is_ important.
