+ * Framework class for strings that involve multiple values.

+ * Certain CSS properties such as border-width and margin allow multiple
+ * lengths to be specified. This class can take a vanilla border-width
+ * definition and multiply it, usually into a max of four.
+ *
+ * @note Even though the CSS specification isn't clear about it, inherit
+ * can only be used alone: it will never manifest as part of a multi
+ * shorthand declaration. Thus, this class does not allow inherit.
