Changes
/* Node styles */
* a <del>strikethrough</del> node text means that the corresponding {{UBIK}} object was deleted somewhere outside of this control. Once you refresh the node, i.e. by collapsing and expanding its parent node, it will disappear
* an ''italic'' node text means that the corresponding {{UBIK} object doesn't derive (or instance, depending on the view mode) directly from the hierachical parent, but is inherited
* a <span style="color:gray;">gray</span> node text means that the corresponding {{UBIK}} is locked against modifications
* a <span style="color:red;">red</span> node text means that the corresponding {{UBIK}} object violates one of the [[Rule|rules]] that were assigned to it
