Register the specified DTD URL for the specified public identifier. This must be called before the first call to parse().
Digester contains an internal EntityResolver implementation. This maps PUBLICID's to URLs (from which the resource will be loaded). A common use case for this method is to register local URLs (possibly computed at runtime by a classloader) for DTDs. This allows the performance advantage of using a local version without having to ensure every SYSTEM URI on every processed xml document is local. This implementation provides only basic functionality. If more sophisticated features are required, using {@link #setEntityResolver} to set a custom resolver is recommended.
Note: This method will have no effect when a custom EntityResolver has been set. (Setting a custom EntityResolver overrides the internal implementation.)
@param publicId Public identifier of the DTD to be resolved
@param entityURL The URL to use for reading this DTD
