Well, the basic rule is, if a problem doesn't show up, with xmllint,
it's most probably due to an inapropriate usage of the library.

cat ~/x.xml
<?xml version="1.0"?>
<!DOCTYPE foo [
<!ELEMENT foo (bar)>
<!ELEMENT bar (#PCDATA)>
]>
<foo>foo</foo>

./xmllint --valid ~/x.xml
/home/morus/x.xml:6: element foo: validity error : Element foo content does not follow the DTD, expecting 
(bar), got (CDATA)
<foo>foo</foo>
              ^
./xmllint --version
lt-xmllint: using libxml version 20602
   compiled with: DTDValid FTP HTTP HTML C14N Catalog XPath XPointer XInclude Iconv Unicode Regexps Automata 
Schemas 

I'm not familiar enough with the C API to guess what might be wrong in your
code, but you might have a look at xmllints sources, to see how validation 
is done.
