+        HTML 3.2 aims to capture recommended practice as of early '96
+        and as such to be used as a replacement for HTML 2.0 (RFC 1866).
+        Widely deployed rendering attributes are included where they
+        have been shown to be interoperable. SCRIPT and STYLE are
+        included to smooth the introduction of client-side scripts
+        and style sheets. Browsers must avoid showing the contents
+        of these element Otherwise support for them is not required.
+        ID, CLASS and STYLE attributes are not included in this version
+        of HTML.

+    This is HTML 4.0 Strict DTD, which excludes the presentation 
+    attributes and elements that W3C expects to phase out as 
+    support for style sheets matures. Authors should use the Strict
+    DTD when possible, but may use the Transitional DTD when support
+    for presentation attribute and elements is required.
+    
+    HTML 4.0 includes mechanisms for style sheets, scripting,
+    embedding objects, improved support for right to left and mixed
+    direction text, and enhancements to forms for improved
+    accessibility for people with disabilities.

+    This is HTML 4.01 Strict DTD, which excludes the presentation 
+    attributes and elements that W3C expects to phase out as 
+    support for style sheets matures. Authors should use the Strict
+    DTD when possible, but may use the Transitional DTD when support
+    for presentation attribute and elements is required.
+    
+    HTML 4 includes mechanisms for style sheets, scripting,
+    embedding objects, improved support for right to left and mixed
+    direction text, and enhancements to forms for improved
+    accessibility for people with disabilities.
