   I confirm that if I remove the delegateSystem from 
/etc/xml/nextcatalog.xml and fix /etc/xml/testxhtml.xml to have the uri
point to the /usr/share/sgml/xhtml1/xhtml1-20020801/DTD/xhtml1-strict.dtd
file found on my system the DTD is correctly found:

paphio:~/XML -> xmllint --valid --noout --nonet tst.xml
tst.xml:7: element html: validity error : Element html content does not follow the DTD, expecting (head , 
body), got (head )
</html>
       ^
paphio:~/XML ->

  It really seems to boil down to a misunderstanding in the way XML Catalog
resolution works.
