filtering. The print system does not verify that the filter specified is known
to the supervisor when the document is submitted.
translation-filter Document Attribute
Users can specify the translation-filter document attribute to override
the automatic invocation of a translation filter when more than one filter
is available that can perform the specified translation. If this attribute is
specified, the value of this attribute is the name of a filter that is applied
to the document data regardless of the value of the document-format and
native-document-formats-ready attributes.
no-filtering Document Attribute
Users can specify the Boolean document attribute, no-filtering,to
disable both translation and modification filtering. If the no-filtering
attribute is true, the server invokes no translation filters and ignores the
value of the modification-filter attribute.
8.1.2 Command Text Processing
The command field of the filter-definition attribute contains the
command that the supervisor executes to invoke the filter. This command
field can contain variables that name attribute values. The supervisor
replaces the variables with corresponding attribute values. The syntax for a
substitution field is:
#{attribute-name,[default-value], [substitution-expression]}
Items in square brackets are optional. The default-value and
substitution- expression fields can be empty strings. The attribute
name can be any of the document attributes listed in Table 8–1. The
supervisor replaces the substitution field with one of the following:
• The value of the named attribute, if it has a defined value, and if the
substitution field is not present (fewer than two commas).
• The characters in the default-value field, if the attribute is not
defined, and the default-value field is present (at least one comma
after attribute-name).
• The evaluated substitution-expression field if it is present and the
attribute is defined.
Attribute names and values cannot be abbreviated. If the attribute
has no value and default-value is specified, the supervisor replaces the
substitution-expression field with a default-value. If the attribute has
