When processing a reference to an external entity whose declaration contains a public identifier but no system
identifier, OmniMark must be told how to locate the entity's replacement value. A
performs this function.
library declarations can also be used by OmniMark in a library file specified on the command line by
-library command-line option. A library file can be used either while an OmniMark program is
being run or while a DTD is being compiled. It gives public/system identifier bindings that are only used during
For example, if a DTD is being compiled with the OmniMark program on one computer, and if the result will be
used on another computer (that may have a different directory structure), it is usually appropriate to put the
library file declaration in library files during each of the runs.
This example of a
library declaration could be used to locate the entity sets for alphabetic characters
defined in Annex D of ISO 8879.
