DTD auto elements

[paetje]

I mad a DTD witch is currentley in use , but I want to optimise this DTD so no mistakes can be made. This is my DTD:

<!ELEMENT website (titel?, pagina?)>	<!ELEMENT titel  (#PCDATA)>	<!ELEMENT pagina (paginatitel?, content?, overig?)>  <!ELEMENT paginatitel (#PCDATA)>    <!ELEMENT content (alinea*)> 	 <!ELEMENT alinea (#PCDATA, nadruk*, tekstlink*, afbeelding*, lijst*, subalinea*)>    <!ELEMENT nadruk (#PCDATA)>    <!ELEMENT tekstlink (#PCDATA)>    <!ELEMENT afbeelding (img+, alt+)>   	 <!ELEMENT img (#PCDATA)>   	 <!ELEMENT alt (#PCDATA)>    <!ELEMENT lijst (item+, itemlink*)>   	 <!ELEMENT item (#PCDATA)>   	 <!ELEMENT itemlink (#PCDATA)>    <!ELEMENT subalinea (nadruk*)>  <!ELEMENT overig (links*, objecten*)> 	  	 <!ELEMENT links (kop, link+)>    <!ELEMENT kop (#PCDATA)>    <!ELEMENT link (#PCDATA)> 	 <!ELEMENT object (objectnaam)>    <!ELEMENT objectnaam (#PCDATA)>

This DTD is used on the program XMetal. When I make a blanc document I get all elements to choose from. But I want a standard document witch contains a couple of set elements. This elements supposed to be: website, titel, pagina, paginatitel, content, overig. On this way I get these elements witch are needed to create a valide page. So the people who will work with this DTD only have to fill in these elements.Does anyone know how I can make this happen?

I made a couple little changes, all my elements are working the way I want. Only one thing doesn't work. My parent element <website> has to appear automaticley after opening a new file.
