Class Pxp_reader.lookup_system_id_as_file

class lookup_system_id_as_file : ?fixenc:Pxp_types.encoding -> (string * string) list -> resolver
Looks up resolvers for URL identifiers: The catalog argument specifies pairs (url, filename) mapping URL's to filenames. The filenames must already be encoded in the character set the system uses for filenames.

Note: URL's are simply compared literally, without making relative IDs absolute. See norm_system_id below for improving this.

fixenc: Overrides the encoding of the file contents. By default, the standard rule is applied to find out the encoding of the file.
