2 This is the entities DTD for Voyager. It is derived from
|
|
|
3 the HTML 4.0 strict DTD with a few changes to make it simple
|
|
|
4 to formalize as XML. It should be included before any element
|
|
|
5 declarations as it defines entities for the content models used
|
|
|
6 by most elements in Voyager.
