  in libxml2 validating does not do defaulting at the tree level,
attribute defaulting is a separate operation:

paphio:~/XML -> xmllint --valid --shell tst.xml
/ > xpath /test_unit[ st=0]
Object is a Node Set :
Set contains 0 nodes:
/ > paphio:~/XML ->
paphio:~/XML -> xmllint --dtdattr --shell tst.xml
/ > xpath /test_unit[ st=0]
Object is a Node Set :
Set contains 1 nodes:
1  ELEMENT test_unit
    ATTRIBUTE st
      TEXT
        content=0
/ > paphio:~/XML ->

Instead of asking for default validation just ask for DTD loading and
attribute completion:

xmlLoadExtDtdDefaultValue |= XML_DETECT_IDS | XML_COMPLETE_ATTRS;

this should work.
