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 Internal Standard ISO/IEC 10744 -- Hypermedia/Time-based Structuring Language
The following options are available:
-bbctf, --bctf=bctf, -bencoding, --encoding=encoding
If -tfilename is also specified, then the specified filename will be prefixed to the sysid to make the filename for the RAST result for each sysid.
<!ENTITY % name "INCLUDE">
occurs at the start of the document type declaration subset in the SGML document entity. Since repeated definitions of an entity are ignored, this definition will take precedence over any other definitions of this entity in the document type declaration. Multiple -i options are allowed. If the SGML declaration replaces the reserved name INCLUDE then the new reserved name will be the replacement text of the entity. Typically the document type declaration will contain
<!ENTITY % name "IGNORE">
and will use %name; in the status keyword specification of a marked section declaration. In this case the effect of the option will be to cause the marked section not to be ignored.
entity Output definitions of all general entities not just for data or subdoc entities that are referenced or named in an ENTITY or ENTITIES attribute.
id Distinguish attributes whose declared value is ID.
line Output L commands giving the current line number and filename.
included Output an i command for included sub-elements.
empty Output an e command for elements which are not allowed to have an end-tag, that is those with a declared content of empty or with a content reference attribute.
notation-sysid Output an f command before an N command, if a system identifier could be generated for that notation.
nonsgml In fixed character set mode, output \% escape sequences for non-SGML data characters. Non-SGML data characters can result from numeric character references.
data-attribute Output the notation name and attributes for DATA attributes. Otherwise, DATA attributes are treated like CDATA attributes. For more details see clause 4.4.3 of Annex K of ISO 8879.
comment Output an _ command with the contents of a comment. Multiple comments in a single comment declaration will result in multiple distinct _ commands, just as if the comments were each in a separate comment declaration.
omitted Output an o command before a command which was implied by the input document, but omitted from the actual markup. This currently affects (,), and A commands.
tagomit As omitted, but only for ( and ) commands.
attromit As omitted, but only for A commands.
Multiple -o options are allowed.
xml Warn about constructs that are not allowed by XML.
mixed Warn about mixed content models that do not allow #PCDATA anywhere.
sgmldecl Warn about various dubious constructions in the SGML declaration.
should Warn about various recommendations made in ISO 8879 that the document does not comply with. (Recommendations are expressed with "should", as distinct from requirements which are usually expressed with "shall".)
default Warn about defaulted references.
duplicate Warn about duplicate entity declarations.
undefined Warn about undefined elements: elements used in the DTD but not defined.
unclosed Warn about unclosed start and end-tags.
empty Warn about empty start and end-tags.
net Warn about net-enabling start-tags and null end-tags.
min-tag Warn about minimized start and end-tags. Equivalent to combination of unclosed, empty and net warnings.
unused-map Warn about unused short reference maps: maps that are declared with a short reference mapping declaration but never used in a short reference use declaration in the DTD.
unused-param Warn about parameter entities that are defined but not used in a DTD. Unused internal parameter entities whose text is INCLUDE or IGNORE won't get the warning.
notation-sysid Warn about notations for which no system identifier could be generated.
all Warn about conditions that should usually be avoided (in the opinion of the author). Equivalent to: mixed, should, default, undefined, sgmldecl, unused-map, unused-param, empty and unclosed.
immediate-recursion Warn about immediately recursive elements. For more detais see clause 2.2.5 of Annex K of ISO 8879.
fully-declared Warn if the document instance fails to be fully declared. This has the effect of changing the SGML declaration to specify IMPLYDEF ATTLIST NO ELEMENT NO ENTITY NO NOTATION NO. For more details see clause 2.2.1 of Annex K of ISO 8879.
fully-tagged Warn if the document instance fails to be fully-tagged. This has the effect of changing the SGML declaration to specify DATATAG NO, RANK NO, OMITTAG NO, SHORTTAG STARTTAG EMPTY NO and SHORTTAG ATTRIB OMITNAME NO. For more details see clause 2.2.2 of Annex K of ISO 8879.
amply-tagged, amply-tagged-recursive Warn if the doucment instance fails to be amply-tagged. Implicitly defined elements may be immediately recurisve if amply-tagged-recursive is specified. This has the effect of changing the SGML declaration to specify DATATAG NO, RANK NO, OMITTAG NO, SHORTTAG ATTRIB OMITNAME NO and either IMPLYDEF ELEMENT ANYOTHER or IMPLYDEF ELEMENT YES. For more details see clause 2.2.4 of Annex K of ISO 8879.
type-valid Warn if the document instance fails to be type-valid. This has the effect of changing the SGML declaration to specify VALIDITY YES. For more details see clause 2.2.3 of Annex K of ISO 8879.
entity-ref Warn about references to non-predefined entities. This has the effect of changing the SGML declaration to specify ENTITIES REF NONE. For more details see clause 2.3.2 of Annex K of ISO 8879.
external-entity-ref Warn about references to external entities. This includes references to an external DTD subset. This has the effect of changing the SGML declaration to specify ENTITIES REF INTERNAL. For more details see clause 2.3.3 of Annex K of ISO 8879.
integral Warn if the document instance is not integrally stored. This has the effect of changing the SGML declaration to specify ENTITIES INTEGRAL YES. For more details see clause 2.3.1 of Annex K of ISO 8879.
A warning can be disabled by using its name prefixed with no-. Thus -wall -wno-duplicate will enable all warnings except those about duplicate entity declarations.
The following values for warning_type disable errors:
no-idref Do not give an error for an ID reference value which no element has as its ID. The effect will be as if each attribute declared as an ID reference value had been declared as a name.
no-significant Do not give an error when a character that is not a significant character in the reference concrete syntax occurs in a literal in the SGML declaration. This may be useful in conjunction with certain buggy test suites.
no-valid Do not require the document to be type-valid. This has the effect of changing the SGML declaration to specify VALIDITY NOASSERT and IMPLYDEF ATTLIST YES ELEMENT YES. An option of -wvalid has the effect of changing the SGML declaration to specify VALIDITY TYPE and IMPLYDEF ATTLIST NO ELEMENT NO. If neither -wvalid nor -wno-valid are specified, then the VALIDITY and IMPLYDEF specified in the SGML declaration will be used.
no-afdr Do not give errors when AFDR meta-DTD notation features are used in the DTD. These errors are normally produced when parsing the DTD, but suppressed when parsing meta-DTDs.
The following options are also supported for backward compatibility with sgmls:
