library (public-identifier system-identifier)+


The library declaration is used to map the public identifier of an SGML/XML external entity to a system identifier (system filename containing replacement text). In the library declaration, the public-identifiers and the system-identifiers are quoted strings:

  library "-//ES//DTD for foo//EN" "foo.dtd"
          "-//ES//TEXT for bar//EN" "bar.txt"
          "-//ES//TEXT for baz//EN" "baz.txt"
          "-//ES//TEXT for bat//EN" "bat.txt"

There can be any number of library declarations in a program, but each public-identifier should have only one definition.

Note that library declarations can be put into a separate file, external to the main program, which can be referenced using the -library command-line option. Entries in the library file always take precedence over those in the OmniMark program.

OmniMark will look for the system identifier in the following order:

  1. the current directory,
  2. the directory referenced in the library declaration, and
  3. the path indicated in the -libpath command-line option.
