A correction:
Addititon of

<!ENTITY % boolean "(true|false)">

<!ELEMENT preferences (module+)>
<!ELEMENT module (head, category+, pref+)>
  <!-- think of a file, not necessarily a Mozilla module -->
<!ELEMENT head (scope, owner, additionalinfo?)>
  <!-- rename, if namespace collision with xhtml -->
<!ELEMENT scope CDATA>     <!-- e.g. Component -->
<!ELEMENT owner #PCDATA>
<!ELEMENT additionalinfo &xhtml;>

and change of

<!ELEMENT type
<!ATTLIST type
  of (Boolean|Integer|URL|String) #REQUIRED
>
<!ELEMENT option (value, explanation?)>

to

<!ELEMENT type EMPTY>
<!ATTLIST type
  of (boolean|integer|url|string) #REQUIRED
  limited %boolean; "false"
>     <!-- limited: only in the database listed options can be used -->
<!ELEMENT option (value, explanation?)>
<!ATTLIST
  default %boolean; "false"
>   <!-- default: only one option can have default="true" -->

and <!ENTITY % xhtml #PCDATA> to <!ENTITY % xhtml ANY>

Open issues:
I don't know, how to integrate the XHTML spec into this definition.
Wording of "explanation"

Here is an example for an usage of the DTD:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE greeting SYSTEM
