In contrary to {@link module:engine/model/node~Node nodes}, which are building blocks of\n * model document tree, markers are not stored directly in document tree but in\n * {@link module:engine/model/model~Model#markers model markers' collection}. Still, they are document data, by giving\n * additional meaning to the part of a model document between marker start and marker end.\n *\n * In this sense, markers are similar to adding and converting attributes on nodes. The difference is that attribute is\n * connected with a given node (e.g. a character is bold no matter if it gets moved or content around it changes).\n * Markers on the other hand are continuous ranges and are characterized by their start and end position. This means that\n * any character in the marker is marked by the marker. For example, if a character is moved outside of marker it stops being\n * \"special\" and the marker is shrunk. Similarly, when a character is moved into the marker from other place in document\n * model, it starts being \"special\" and the marker is enlarged.\n *\n * Another upside of markers is that finding marked part of document is fast and easy. Using attributes to mark some nodes\n * and then trying to find that part of document would require traversing whole document tree. Marker gives instant access\n * to the range which it is marking at the moment.\n *\n * Markers are built from a name and a range.\n *\n * Range of the marker is updated automatically when document changes, using\n * {@link module:engine/model/liverange~LiveRange live range} mechanism.\n *\n * Name is used to group and identify markers. Names have to be unique, but markers can be grouped by\n * using common prefixes, separated with `:`, for example: `user:john` or `search:3`. That's useful in term of creating\n * namespaces for custom elements (e.g. comments, highlights). You can use this prefixes in\n * {@link module:engine/model/markercollection~MarkerCollection#event:update} listeners to listen on changes in a group of markers.\n * For instance: `model.markers.on( 'update:user', callback );` will be called whenever any `user:*` markers changes.\n *\n * There are two types of markers.\n *\n * 1. Markers managed directly, without using operations. They are added directly by {@link module:engine/model/writer~Writer}\n * to the {@link module:engine/model/markercollection~MarkerCollection} without any additional mechanism. They can be used\n * as bookmarks or visual markers. They are great for showing results of the find, or select link when the focus is in the input.\n *\n * 1. Markers managed using operations. These markers are also stored in {@link module:engine/model/markercollection~MarkerCollection}\n * but changes in these markers is managed the same way all other changes in the model structure - using operations.\n * Therefore, they are handled in the undo stack and synchronized between clients if the collaboration plugin is enabled.\n * This type of markers is useful for solutions like spell checking or comments.\n *\n * Both type of them should be added / updated by {@link module:engine/model/writer~Writer#addMarker}\n * and removed by {@link module:engine/model/writer~Writer#removeMarker} methods.\n *\n *\t\tmodel.change( ( writer ) => {\n * \t\t\tconst marker = writer.addMarker( name, { range, usingOperation: true } );\n *\n * \t\t\t// ...\n *\n * \t\t\twriter.removeMarker( marker );\n *\t\t} );\n *\n * See {@link module:engine/model/writer~Writer} to find more examples.\n *\n * Since markers need to track change in the document, for efficiency reasons, it is best to create and keep as little\n * markers as possible and remove them as soon as they are not needed anymore.\n *\n * Markers can be downcasted and upcasted.\n *\n * Markers downcast happens on {@link module:engine/conversion/downcastdispatcher~DowncastDispatcher#event:addMarker} and\n * {@link module:engine/conversion/downcastdispatcher~DowncastDispatcher#event:removeMarker} events.\n * Use {@link module:engine/conversion/downcasthelpers downcast converters} or attach a custom converter to mentioned events.\n * For {@link module:engine/controller/datacontroller~DataController data pipeline}, marker should be downcasted to an element.\n * Then, it can be upcasted back to a marker.
