This function allows you to declare a graphic entity with a specific name and a specific notation.

name is the name of an existing graphic file entity. A leading & is optional.

notn is the name of the graphic entity's notation. A notation can associate a graphics application with a specific type of graphic file.

sysid is the new system identifier value (if there is one).

pubid is the new public identifier value (if there is one).

doc is the document identifier. By default the current document is assumed.

confirmDtdOverride prompts the user whether to override the DTD if the graphic entity is already declared in the DTD. A non-zero value will prompt the user.

inEntity signifies whether the declaration is within an entity. A non-zero value means the declaration is within an entity.
