ISO 12083 is the successor to the Association of American Publishers (AAP) Electronic Publishing Special Interest Group (EPSIG) standard. Four DTDs are included in this package--one for articles, one for books, one for serials, and one for mathematics which may be used in any of the other three.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
