    // C.2.  Abnormal Examples
    //   Although the following abnormal examples are unlikely to occur in
    //   normal practice, all URI parsers should be capable of resolving them
    //   consistently.  Each example uses the same base as above.
    //
    //   An empty reference refers to the start of the current document.
    //
    //      <>            =  (current document)
    //
    //   Parsers must be careful in handling the case where there are more
    //   relative path ".." segments than there are hierarchical levels in the
    //   base URI's path.  Note that the ".." syntax cannot be used to change
    //   the authority component of a URI.
    //
    //      ../../../g    =  http://a/../g
    //      ../../../../g =  http://a/../../g
    //
    //   In practice, some implementations strip leading relative symbolic
    //   elements (".", "..") after applying a relative URI calculation, based
    //   on the theory that compensating for obvious author errors is better
    //   than allowing the request to fail.  Thus, the above two references
    //   will be interpreted as "http://a/g" by some implementations.
    //
    //   Similarly, parsers must avoid treating "." and ".." as special when
    //   they are not complete components of a relative path.
    //
    //      /./g          =  http://a/./g
    //      /../g         =  http://a/../g
    //      g.            =  http://a/b/c/g.
    //      .g            =  http://a/b/c/.g
    //      g..           =  http://a/b/c/g..
    //      ..g           =  http://a/b/c/..g
    //
    //   Less likely are cases where the relative URI uses unnecessary or
    //   nonsensical forms of the "." and ".." complete path segments.
    //
    //      ./../g        =  http://a/b/g
    //      ./g/.         =  http://a/b/c/g/
    //      g/./h         =  http://a/b/c/g/h
    //      g/../h        =  http://a/b/c/h
    //      g;x=1/./y     =  http://a/b/c/g;x=1/y
    //      g;x=1/../y    =  http://a/b/c/y
    //
    //   All client applications remove the query component from the base URI
    //   before resolving relative URI.  However, some applications fail to
    //   separate the reference's query and/or fragment components from a
    //   relative path before merging it with the base path.  This error is
    //   rarely noticed, since typical usage of a fragment never includes the
    //   hierarchy ("/") character, and the query component is not normally
    //   used within relative references.
    //
    //      g?y/./x       =  http://a/b/c/g?y/./x
    //      g?y/../x      =  http://a/b/c/g?y/../x
    //      g#s/./x       =  http://a/b/c/g#s/./x
    //      g#s/../x      =  http://a/b/c/g#s/../x
    //
    //   Some parsers allow the scheme name to be present in a relative URI if
    //   it is the same as the base URI scheme.  This is considered to be a
    //   loophole in prior specifications of partial URI [RFC1630]. Its use
    //   should be avoided.
    //
    //      http:g        =  http:g           ; for validating parsers
    //                    |  http://a/b/c/g   ; for backwards compatibility
