+
+  where
+
+    x := major version
+    y := minor version
+
+NOTES:
+  Many of the design patterns used in this DTD were take from the
+  W3C XML Specification DTD edited by Eve Maler <elm@arbortext.com>.
+
+  Where possible, great care has been used to reuse HTML tag
+  names to reduce learning efforts and to allow HTML editors to be
+  used for complex authorings like tables and lists.
+
+EXTENSIBILITY:
+  This DTD includes several empty placeholders that can be used to
+  extend it. These placeholders are implemented with empty entities. Here
+  is the list of those empty entities and what they are used for:
+  
+    - local.inline: this entity should contain extended definitions of 
+                    elements that can be used 'inline', or directly inside
+                    the content. An example for this entity could be 
+
+                        <!ENTITY % local.inline "|citation">
+
+    - local.blocks: this entity should contain extended definitions of
+                    elements that behave as 'blocks', thus can be visually
+                    rendered as areas on the canvas. An example for this
+                    entity could be:
+
+                        <!ENTITY % local.blocks "|poem">
+
+    - local.sections: this entity should contain extended definitions of
+                      elements that behave as 'sections', thus can be considered
+                      containers of block-level elements. An example for
+                      this entity could be:
+
+                        <!ENTITY % local.sections "|chapter">
+
+    - local.headers: this entity should contain extended definitions of
+                     elements that behave as parts of the document header.
+                     An example for this header could be:
+
+                        <!ENTITY % local.headers ", notes?">
+
+    - local.footers: this entity should contain extended definitions of
+                     elements that behave as parts of the document footer.
+                     An example for this header could be:

+  FAQs represent a powerful knowledge base and a very good way of solving

+  be published in other formats as well as enhancing data interchange.

+<!-- ===================================================================
+     
+     Apache JavaDoc DTD (version 0.4-draft)
+
+PURPOSE:
+  This DTD is designed to capture the output of JavaDoc as an XML document
+  through the use of the JavaDocXML Doclet. The hope is that by having the
+  JavaDoc documentation in an XML format, it will be easier for application
+  developers working with XML to treat their java source documentation in the
+  same way they treat any other XML document within their publication framework.
+  
+  This DTD should reflect the information contained within the RootDoc object 
+  passed to the JavaDocXML Doclet by JavaDoc. The RootDoc object and the rest 
+  of the javaDoc Doclet API is specified at
+  
+  http://java.sun.com/products/jdk/1.2/docs/tooldocs/javadoc/doclet/index.html
+  
+  The only information that appears to be difficult to derive from this DTD
+  that is easy to obtain from the RootDoc object is the information about 
+  serialization. However, this information should be derivable by manually 
+  looking for the correct serialization methods and other related structures.
+

+       "-//APACHE//DTD JavaDoc Vx.yz//EN"

+  where 
+  
+    x := major version
+    y := minor version
+    z := status identifier (optional)
+      
+NOTES:  
+  The authors would like to thank the Cocoon's mail list subscribers for 
+  providing such great support and feedback for this DTD.

+     Apache Todos DTD (Version 1.1)
+
+PURPOSE:
+  This DTD was developed to create a simple yet powerful document 
+  type for software development todo lists for use with the Apache projects.  
+  It is an XML-compliant DTD and it's maintained by the Apache XML 
+  project.

+    x := major version
+    y := minor version
+      
+NOTES:  
+  It is important, expecially in open developped software projects, to keep
+  track of software changes that need to be done, planned features, development
+  assignment, etc. in order to allow better work parallelization and create
+  an entry point for people that want to help. This DTD wants to provide
+  a solid foundation to provide such information and to allow it to be
+  published as well as distributed in a common format.
