You forgot to mention the full set of errors
paphio:~/XML -> ./xmllint --noout --dtdvalid a.dtd b.xml
b.xml:2: namespace error : Namespace prefix ns for attr on root is not defined
<root ns:attr="1"/>
^
b.xml:2: element root: validity error : No declaration for attribute attr of
element root
Document b.xml does not validate against a.dtd
paphio:~/XML ->
when you first parsed the document, it uses a namespace, which is undeclared.
So the document is not okay w.r.t. namespaces. The problem is that the prefix
is dropped from the document:
paphio:~/XML -> ./xmllint b.xml
b.xml:2: namespace error : Namespace prefix ns for attr on root is not defined
<root ns:attr="1"/>
^
<?xml version="1.0"?>
<root attr="1"/>
paphio:~/XML ->
Which sounds like a bug but completely unrelated to what you're trying to
link to , it's not at all related to validation (nor postvalidation)
