 <!-- FreeBSD Documentation Project, Extended DocBook DTD
 
      This DTD builds upon the DocBook 3.1 DTD. It extends it in order to
      add some new elements.
 
      The comment style and section headings are drawn from the DocBook DTD.
 
      The FPI for this DTD is "-//FreeBSD//DTD DocBook V3.1-Based Extension//EN"

      Each element has three attributes which specify which version(s) of
      FreeBSD the element's content applies to.  It is up to the
      pre-processor to include or exclude elements based on the value of
      these attributes.                                                     -->

 <!-- Altered general entities ............................................
 
      The HTML 4.0 DTD includes some new ISO entities. Most browsers don't
      support them yet. Change the definition of some of these entities to
      character strings that the browsers will support.
 
      This does not apply when generating printed output, so these are 
      contained within a %output.html; marked section.
 
      As browser technology improves, these definitions can be removed.     -->
