* <h1>ID encoding</h1>
*
*
* <p>
* This is a multi-step process:
* <ul>
* <li>
* <strong>Namespace recognition</strong> -
* If the ID begins with a recognized namespace, then that namespace is
* stripped from the ID, and the prefix associated with that namespace
* is set aside for later in the process.
* </li>
* <li>
* <strong>Rare character encoding</strong> -
* Illegal characters are translated to their hexadecimal equivalents,
* as are some rarely used characters which will be given other
* purposes later in the process. The translated characters include any
* octet outside of the visible ASCII range (21-7e), and these additional
* characters:
* <pre> " * + , &lt; = &gt; ? ^ | \ ~ </pre>
* The hexadecimal encoding consists of a caret followed by 2 hex digits,
* e.g.: ^7C
* </li>
* <li>
* <strong>Common character encoding</strong> -
* To keep the file paths short and readable, characters that are used
* commonly in IDs but may be illegal in the file system are translated
* to a single, lesser-used character.
* <ul>
* <li> / becomes = </li>
* <li> : becomes + </li>
* <li> . becomes , </li>
* </ul>
* </li>
* <li>
* <strong>Prefixing</strong> -
* If a namespace was recognized on the ID in the first step, the
* associated prefix letter will be prepended to the string, with a
* tilde separator.
* </li>
* <li>
* <strong>Path breakdown</strong> -
* Finally, path separator characters are inserted after every third
* character in the processed ID string.
* </li>
* </ul>
* Examples:
* <br/><code>ark:/13030/xt12t3</code> becomes
* <code>ark/+=1/303/0=x/t12/t3</code>
* <br/><code>http://n2t.info/urn:nbn:se:kb:repos-1</code> becomes
