[PHP-DOC] XML DocBook DTD Needed ?

[Anderson Fortaleza]

If i am using a XSLT parser as Xalan, for example, and DocBook 
Stylesheets like N. Walsh stylesheets, do I have to have DocBook DTD 
installed in my computer ? Cos jade uses this catalog file, but I see no 
equal thing under Xalan, just for example "xalan source.xml style.xsl 
target.html" for example. Where are the DocBook DTD needed in this case ?

thx !
Anderson
