| | Web Naming and Addressing Overview (URIs, URLs, ...) |
 | | When embedded within a base document, a URL in its absolute form may contain a great deal of information which is already known from the context of that base document's retrieval, including the scheme, network location, and parts of the url-path. |
 | | In situations where the base URL is well-defined and known to the parser (human or machine), it is useful to be able to embed URL references which inherit that context rather than re-specifying it in every instance. |
 | | This one is ratified as an IETF proposed standard, and it discusses each of the URL schemes (known at that time), but its grammar has some mistakes, and it doesn't cover several aspects of URL syntax, such as relative URLs and fragment identifiers |
