sgml2xml‐isoent − Convert SGML to XML with support for ISO

sgml2xml‐isoent [sgml‐document]

sgml2xml‐isoent converts an SGML document to XML, with
support for the ISO entities.  This is done by using
sgml2xml(1) from the SP package (or osx(1) from the OpenSP
package), and the declaration for the XML version of the ISO
entities is added to the output.  This means that the output
of this conversion should work as‐is with any XML tool.

     This program is often used for processing SGML DocBook
documents with XML‐based tools. In particular,
db2x_xsltproc(1) calls this program as part of its −−sgml
option. On the other hand, it is probably not helpful for
migrating a source SGML text file to XML, since the
conversion mangles the original formatting.

     Since the XML version of the ISO entities are referred
to directly, not via a DTD, this tool also works with
document types other than DocBook.

The ISO entities are referred using the public identifiers
ISO 8879:1986//ENTITIES//...//EN//XML.  The catalogs used
when parsing the converted document should resolve these
entities to the appropriate place (on the local filesystem).
If the entities are not resolved in the catalog, then the
fallback is to get the entity files from the Web site.
