class lookup_public_id_as_file :Makes a resolver for
?fixenc:Pxp_core_types.I.encoding -> (string * string) list ->
PUBLICidentifiers. The list (catalog) argument specifies pairs
PUBLICidentifiers to filenames. The filenames must already be encoded in the character set the system uses for filenames.
There is a restriction of this catalog class:
PUBLIC entity has been opened, it is not possible to refer
to sub entities by relative
SYSTEM names, even if the
name is accompanied by a resovable system name like in
Public(pubid,sysid). Workaround: Use
lookup_id instead, and
put the complete
Public(pubid,sysid) ID's into the catalog.
fixenc: Overrides the encoding of the file contents. By default, the
standard rule is applied to find out the encoding of the file.
