osx - An SGML System Conforming to International Standard ISO 8879 -- Standard Generalized Markup Language
osx [-Cehilprvx] [-bencoding] [-ccatalog_file] [-Ddirectory] [-ffile] [-wwarning_type] [-xxml_output_option...] [sysid...]
osx converts SGML to XML. osx parses and validates the SGML document contained in sysid and writes an equivalent XML document to the standard output. osx will warn about SGML constructs which have no XML equivalent.
The following options are available:
no-nl-in-tag Don't use newlines inside start-tags. Usually osx uses newlines inside start-tags so as to reduce the probability of excessively long lines.
id Output attribute declarations for ID attributes.
notation Output declarations for notations.
ndata Output declarations for external data entities. XML requires these to be NDATA. osx will warn about CDATA and SDATA external data entities and output them as NDATA entities.
cdata Use XML CDATA sections for CDATA marked sections and for elements with a declared content of CDATA.
comment Output comment declarations. Comment declarations in the DTD will not be output.
lower 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.
pi-escape 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.
empty Use the <e/> syntax for element types e declared as EMPTY.
attlis Output an ATTLIST declaration for every element specifying the type of all attributes. The default will always be #IMPLIED.
Multiple -x options are allowed.
