A schema for defining and mapping the services to URLs.

Please note: This structure is not final.


Allowed HTTP method on resources.

<!ENTITY  % HTTP_METHOD "( GET | POST | PUT | DELETE )"              >

A URI Pattern as defined in the URI Template specifications:

<!ENTITY  % URI_PATTERN "CDATA"                                      >

A valid Cache-Control header as specified by HTTP/1.1 - 14.9 Cache-Control .

<!ENTITY  % CACHE_CONTROL "CDATA"                                    >

A string which contain dynamic tokens and is resolved dynamically.

{...} (curly brackets) indicate that the value is dynamically constructed

      - @ prefixes the name config property

      - $ prefixes the name an HTTP parameter

      - # prefixes the name an URL Pattern parameter or a variable

any other value is considered static and transmitted 'as is'.

<!ENTITY  % TOKENIX "CDATA"                                          >
