+ * URIs are essentially structured names for things -- anything. This interface
+ * provides accessors to get the most basic components of an URI.
+ * If you need to change some parts of the URI use nsIURIMutator.
+ * Subclasses, including nsIURL, impose greater structure on the URI.
+ *
+ * This interface follows Tim Berners-Lee's URI spec (RFC3986) [1], where the
+ * basic URI components are defined as such:
+ * <pre>
+ * ftp://username:password@hostname:portnumber/pathname?query#ref
+ * \ / \ / \ / \ /\ / \ / \ /
+ * - --------------- ------ -------- ------- --- -
+ * | | | | | | |
+ * | | | | FilePath Query Ref
+ * | | | Port \ /
+ * | | Host / ------------
+ * | UserPass / |
+ * Scheme / Path
+ * \ /
+ * --------------------------------
+ * |
+ * PrePath
+ * </pre>
+ * The definition of the URI components has been extended to allow for
+ * internationalized domain names [2] and the more generic IRI structure [3].
+ *
+ * [1] https://tools.ietf.org/html/rfc3986
