            whereas FSYS_DEFAULT includes all style bits, combinations of only
            a few style bits are also possible, and are also described.

            @descr  When used to translate a file system path to a file URL,
            the subset of the following productions for which the appropriate
            style bit is set are checked in order (using the conventions of
            RFC 2234, RFC 2396, and RFC 2732; UCS4 stands for any UCS4
            character):

             Production T1 (VOS local; FSYS_VOS only):
                "//." ["/" *UCS4]
              becomes
                "file:///" *UCS4

             Production T2 (VOS host; FSYS_VOS only):
                "//" [host] ["/" *UCS4]
              becomes
                "file://" host "/" *UCS4

             Production T3 (UNC; FSYS_DOS only):
                "\\" [host] ["\" *UCS4]
              becomes
                "file://" host "/" *UCS4
              replacing "\" by "/" within <*UCS4>

             Production T4 (Unix-like DOS; FSYS_DOS only):
                ALPHA ":" ["/" *UCS4]
              becomes
                "file:///" ALPHA ":/" *UCS4
              replacing "\" by "/" within <*UCS4>

             Production T5 (DOS; FSYS_DOS only):
                ALPHA ":" ["\" *UCS4]
              becomes
                "file:///" ALPHA ":/" *UCS4
              replacing "\" by "/" within <*UCS4>

             Production T6 (any):
                *UCS4
              becomes
                "file:///" *UCS4
              replacing the delimiter by "/" within <*UCS4>.  The delimiter is
              that character from the set { "/", "\" } which appears most
              often in <*UCS4> (if FSYS_UNX is not among the style bits, "/"
              is removed from the set; if FSYS_DOS is not among the style
              bits, "\" is removed from the set).  If two or more
              characters appear the same number of times, the character
              mentioned first in that set is chosen.  If the first character
              of <*UCS4> is the delimiter, that character is not copied.

            @descr  When used to translate a file URL to a file system path,
            the following productions are checked in order (using the
            conventions of RFC 2234, RFC 2396, and RFC 2732):
