    129 to separate directories within the jar proper.

    88Notes towards an implementation of URL references to be contained in

    21 We use the term URL to describe the URL Pathnames, even though RFC3986
    22 notes that its use should be obsolete because in the context of Common
    23 Lisp Pathnames all need a lookup mechanism to be resolved or they
    24 wouldn't be of much use.
     21We use the term URL as shorthand in describing the URL Pathnames, even
     22though the corresponding encoding is more akin to a URI as described
     23in RFC3986.

    35353.  Use URL schemes that are understood by the java.net.URL object.

    37     A file specified by URL
     37    Example of a Pathname specified by URL:

    52 7.  DIRECTORY for non-wildcards
     527.  DIRECTORY works for non-wildcards.
    5353
    54548.  URL pathname work as a valid argument for OPEN with :DIRECTION :INPUT.
    … …  
    56569.  Enable the loading of ASDF2 systems referenced by a URL pathname.
    5757
    58 10.  The reserved URL characters (`~`, `/`, `?`, etc.) shall be
    59 encoded in the proper manner on construction of the Pathname.
     5810.  Pathnames constructed with the "file" scheme
     59(i.e. #p"file:/this/file") need to be properly URI encoded according
     60to RFC3986 or otherwise will signal FILE-ERROR. 
    6061
    616211.  The "file" scheme will continue to be represented by an
    62 "ordinary" Pathname.
     63"ordinary" Pathname.  Thus, after construction of a URL Pathname with
     64the "file" scheme, the namestring of the resulting PATHNAME will no
     65longer contain the "file:" prefix.
    6366
    646712.  The "jar" scheme will continue to be represented by a jar

     129
     13026 NOV 2010 Changed implemenation to use URI encodings for the "file"
     131  schemes including those nested with the "jar" scheme by like
     132  aka. "jar:file:/location/of/some.jar!/".
