[xml] xmllint --nowarning = no information

["Bob Stayton" <bobs sagehill net>]

I've noticed that when I used xmllint --valid to validate a document, if I 
don't use the --nowarning option I get a full description of an invalid 
element that helps me find the error:

ch01.xml:125: element chapter: validity error : Element chapter content 
does
not follow the DTD, expecting (title , (((itemizedlist | orderedlist | 
caution |
note | tip | programlisting | para | blockquote | informalexample | 
graphic | i
nformaltable | example | figure | table | procedure | bridgehead | remark)+ 
, se
ction*) | section+)), got (title indexterm para section section section )
</chapter>
         ^

When I add the --nowarning option to xmllint, I get only this output:

ch01.xml:125: element chapter: validity error : Element chapter content 
does
not follow the DTD
</chapter>
         ^

This is not a warning, this is a validation error.  Why would --nowarning 
suppress this useful information?
In this case, I need to use --nowarning because the DTD in question is 
structured to specify the same attribute more than once.  That generates a 
warning (not an error) that I want to suppress.

Is there any way to use --nowarning and still get the full error output? 
My version is on Windows XP:

xmllint.exe: using libxml version 20626CVS2823
