  35  * Extract components of a "corbaname" URL.
  36  *
  37  * The format of an corbaname URL is defined in INS 99-12-03 as follows.
  38  *<p>
  39  * corbaname url = "corbaname:" <corbaloc_obj> ["#" <string_name>]
  40  * corbaloc_obj  = <obj_addr_list> ["/" <key_string>]
  41  * obj_addr_list = as defined in a corbaloc URL
  42  * key_string    = as defined in a corbaloc URL
  43  * string_name   = stringified COS name | empty_string
  44  *<p>
  45  * Characters in <string_name> are escaped as follows.
  46  * US-ASCII alphanumeric characters are not escaped. Any characters outside
  47  * of this range are escaped except for the following:

  48  *        ; / : ? @ & = + $ , - _ . ! ~ * ; ( )

  49  * Escaped characters is escaped by using a % followed by its 2 hexadecimal
  50  * numbers representing the octet.
  51  *<p>
  52  * The corbaname URL is parsed into two parts: a corbaloc URL and a COS name.
  53  * The corbaloc URL is constructed by concatenation "corbaloc:" with
  54  * <corbaloc_obj>.
  55  * The COS name is <string_name> with the escaped characters resolved.
  56  *<p>
  57  * A corbaname URL is resolved by:
  58  *<ol>
  59  *<li>Construct a corbaloc URL by concatenating "corbaloc:" and <corbaloc_obj>.
  60  *<li>Resolve the corbaloc URL to a NamingContext by using

  61  *     nctx = ORB.string_to_object(corbalocUrl);
  62  *<li>Resolve <string_name> in the NamingContext.
  63  *</ol>
