To identify a digital object:
  Syntax:
    "info:fedora/" object-pid
  Where:
    "object-pid" is the Fedora PID of the object
  Examples:
    info:fedora/example:1
    info:fedora/example:9876

To identify a dissemination:
  Syntax:
    "info:fedora/" object-pid "/" dissem-name
  Where:
    "object-pid" is the Fedora PID of the object (or "*" when the
      URI indicates a dissemination without regard to
      a particular object).
    "dissem-name" is either a datastream ID or behavior definition
      object PID, followed by "/", followed by a method name.
  Examples:
    info:fedora/example:3/DS1
    info:fedora/example:3/example:1/index
    info:fedora/*/DS1
    info:fedora/*/example:1/index

Note that datastream ids and method names may consist of XML NCName
characters.  NCName characters that are not safe to directly encode
in an "info" uri and must be escaped using one to four escaped UTF-8
octets per character, each of the form "%" HEXDIG HEXDIG.

- Make all characters up to and including the PID lowercase.
- Un-escape any URI-escaped characters that do not need escaping
  according the definition of the "info" scheme.
- Make all remaining escaped octets use UPPERCASE (%ff becomes %FF)
