  unclear... 

paphio:~/XML -> cat tst.xml
<?xml version="1.0"?>
<!DOCTYPE note SYSTEM "sample.dtd">
<note>
 <from/>
</note>
 
 
paphio:~/XML -> cat sample.dtd
<!ELEMENT note (to,from,heading,body)>
<!ELEMENT to (#PCDATA)>
<!ELEMENT from (#PCDATA)>
<!ELEMENT heading (#PCDATA)>
<!ELEMENT body (#PCDATA)>
 
paphio:~/XML ->

paphio:~/XML -> xmllint --valid --noout tst.xml
tst.xml:5: element note: validity error : Element note content does not follow the DTD, expecting (to , from 
, heading , body), got (from )
</note>
       ^
paphio:~/XML -> 

   that use the normal DTD validation process, while parsing and raises
the error.

paphio:~/XML -> xmllint --postvalid --noout tst.xml
tst.xml:3: element note: validity error : Element note content does not follow the DTD, expecting (to , from 
, heading , body), got (from )
Document tst.xml does not validate
paphio:~/XML -> 

  That use xmlValidateDtd() post-validation (which is not DTD validation
as defined by the spec). 
  In both case xmllint, using libxml2 indicates the document is not valid.
