 DESCRIPTION
     Decodes a property list from a binary buffer. The contents of the buffer
     contain the values for the correponding properties of the plist. The decode 
     callback of a certain property decodes its value from the buffer and sets it
     in the property list.
 GLOBAL VARIABLES
 COMMENTS, BUGS, ASSUMPTIONS
     Properties in the property list that are not encoded in the serialized
     form retain their default value.
