NAME

SYNOPSIS

DESCRIPTION

spam(1) is another SGML tag normalizer from the same software suite.

OPTIONS

-c catalog-file

Provide the full path name of the SGML catalog file, which is needed to relate the document type name in the initial SGML

<!DOCTYPE document-type-name PUBLIC ``...\''>

declaration to a grammar file that defines the syntax of the SGML tags in the remainder of the file.

This option is always required, because the current version of sgmlnorm has no built-in default catalog location.

At some UNIX sites, a suitable option will be -c /usr/local/lib/html-check/lib/catalog

-d directory-name

Add a file directory name to the default search path used to locate files specified in system identifiers in

<!DOCTYPE document-type-name SYSTEM  ``filename''>

declarations. Multiple -d options are allowed.

-e

Describe open entities in error messages. Error messages always include the position of the most recently opened external entity.

-k cm

This option requires either c, or m, or both, in either order. The letter c requests output of any embedded SGML comments; otherwise, comments are normally discarded. The letter m requests output of marked sections. [It is unclear what the m option is supposed to do.]

-w warning_type

Control warnings and errors. Multiple -w options are allowed. The following values of warning_type enable warnings:

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.

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.

A warning can be disabled by using its name prefixed with no-. Thus -wall 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.
