perl-XML-Catalog Resolve public identifiers and remap system identifiers This module implements draft 0.4 of John Cowan's XML Catalog (formerly known as XCatalog) proposal (). Catalogs may be written in either SOCAT or XML syntax (see the proposal for syntax details); XML::Catalog will assume SOCAT syntax if the catalog is not in well-formed XML syntax. This module, as of 1.0.0, also supports Oasis XML catalogs.
