<title>Description</title>
<para>
<command>osx</command> converts SGML to XML. <command>osx</command> parses and validates the SGML document
contained in <cmdsynopsis><arg rep="repeat"><option><replaceable>sysid</replaceable></option></arg></cmdsynopsis> and writes an equivalent XML document to the
standard output. <command>osx</command> will warn about SGML constructs which have no XML
equivalent.
</para>
<para>Part of an SGML System Conforming to International Standard ISO 8879 -- Standard Generalized Markup Language. An SGML Extended Facilities system conforming to Annex A of International Standard ISO/IEC 10744 -- Hypermedia/Time-based Structuring Language.</para>

<listitem>
<para>
Control the XML output according to the value of
<replaceable>xml_output_option</replaceable> as follows:
</para>
<para><option>no-nl-in-tag</option>
Don't use newlines inside start-tags.
Usually <command>osx</command> uses
newlines inside start-tags so as to reduce the
probability of excessively long lines.
</para>
<para><option>id</option>
Output attribute declarations for ID attributes.
</para>
<para><option>notation</option>
Output declarations for notations.
</para>
<para><option>ndata</option>
Output declarations for external data entities.
XML requires these to be NDATA.
<command>osx</command> will warn about CDATA and
SDATA external data entities and output them as NDATA
entities.
</para>
<para><option>cdata</option>
Use XML CDATA sections for CDATA marked sections and for
elements with a declared content of CDATA.
</para>
<para><option>comment</option>
Output comment declarations. Comment declarations in the
DTD will not be output. </para>
<para><option>lower</option>
Prefer lower case. Names that were subjected to
upper-case substitution by SGML will be folded to lower
case. This does not include reserved names; XML requires
these to be in upper-case.
</para>
<para><option>pi-escape</option>
Escape &<> in the contents of processing instructions
using the amp, lt and gt entities. This allows processing
instructions to contain the string >?, but requires that
applications handle the escapes.
</para>
<para><option>empty</option>
Use the <e/> syntax for element types e declared as EMPTY.
</para>
<para><option>attlist</option>
Output an ATTLIST declaration for every element specifying
the type of all attributes. The default will always be
#IMPLIED.
</para>
<para><option>report-input-sources</option>
Output a processing instruction to report when an input
source other than the main file is opened or closed in the
instance. Do not report any input source changes in
the DTD.</para>
<para><option>report-entities</option>
Output a processing instruction to report when an external
entity reference has been resolved in the instance.
Do not report any entity resolutions in the DTD.</para>
<para><option>no-expand-external</option>
Preserve external entities, write a declaration driver
file named "extEntities.dtf", and include that file
in the instance's internal subset.</para>
<para><option>no-expand-internal</option>
Preserve internal entities, write a declaration driver file
named "intEntities.dtf", and include that file in the
instance's internal subset.</para>
<para><option>no-external-decl</option>
Do not include the external entities declaration driver file
in the instance's internal subset.</para>
<para><option>no-internal-decl</option>
Do not include the internal entities declaration driver file
in the instance's internal subset.</para>
<para><option>no-output-outside-outdir</option>
When preserving external entities, do not write output files
outside the specified output directory ("." by default).
In other words, if an external entity's system identifier
includes enough instances of ".." to cause osx to write
a file outside (above) the output directory, exit (by default
osx will issue a warning but will write the file and
continue.</para>
<para><option>no-overwrite</option>
When preserving internal or external entities, multiple
output files will be written. If this option is specified,
do not overwrite existing files; instead, attempt to append
a number to the end of the original filename to create a
unique filename. Exit with an error if too many (100)
such files already exist.</para>
<para><option>preserve-case</option>
Preserve casing as specified in the DTD for element names;
attribute names; attribute values which are token lists.</para>
<para><option>sdata-as-pis</option>
When translating SDATA entities (whether expanding them or
providing a definition for them in the output's internal
subset), express them as processing instructions instead
of as general internal entities.</para>
<para>Multiple <option>-x</option> options are allowed. </para>
