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. =head1 AUTHOR Current Author: Jeff Fearn Ejfearn@cpan.orgE.
