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

name is the name of an existing notation. A leading & is optional.

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 notation is already declared in the DTD. A non-zero value will prompt the user.
