 The d3.ns.prefix namespace prefix map has been renamed to [d3.namespaces](https://github.com/d3/d3-selection#namespaces), and the d3.ns.qualify method has been renamed to [d3.namespace](https://github.com/d3/d3-selection#namespace). Several new low-level methods are now available, as well. [d3.matcher](https://github.com/d3/d3-selection#matcher) is used internally by [*selection*.filter](https://github.com/d3/d3-selection#selection_filter); [d3.selector](https://github.com/d3/d3-selection#selector) is used by [*selection*.select](https://github.com/d3/d3-selection#selection_select); [d3.selectorAll](https://github.com/d3/d3-selection#selectorAll) is used by [*selection*.selectAll](https://github.com/d3/d3-selection#selection_selectAll); [d3.creator](https://github.com/d3/d3-selection#creator) is used by [*selection*.append](https://github.com/d3/d3-selection#selection_append) and [*selection*.insert](https://github.com/d3/d3-selection#selection_insert). The new [d3.window](https://github.com/d3/d3-selection#window) returns the owner window for a given element, window or document. The new [d3.customEvent](https://github.com/d3/d3-selection#customEvent) temporarily sets [d3.event](https://github.com/d3/d3-selection#event) while invoking a function, allowing you to implement controls which dispatch custom events; this is used by [d3-drag](https://github.com/d3/d3-drag), [d3-zoom](https://github.com/d3/d3-zoom) and [d3-brush](https://github.com/d3/d3-brush).
 
-For the sake of parsimony, the multi-value map methods have been extracted to [d3-selection-multi](https://github.com/d3/d3-selection-multi) and are no longer part of the default bundle. The multi-value map methods have also been renamed to plural form to reduce overload: [*selection*.attrs](https://github.com/d3/d3-selection-multi#selection_attrs), [*selection*.styles](https://github.com/d3/d3-selection-multi#selection_styles) and [*selection*.properties](https://github.com/d3/d3-selection-multi#selection_properties).
+For the sake of parsimony, the multi-value methods—where you pass an object to set multiple attributes, styles or properties simultaneously—have been extracted to [d3-selection-multi](https://github.com/d3/d3-selection-multi) and are no longer part of the default bundle. The multi-value map methods have also been renamed to plural form to reduce overload: [*selection*.attrs](https://github.com/d3/d3-selection-multi#selection_attrs), [*selection*.styles](https://github.com/d3/d3-selection-multi#selection_styles) and [*selection*.properties](https://github.com/d3/d3-selection-multi#selection_properties).
