   Yes libxml2 will parse the cocument if it is well-formed for XML-1.0
you will get non-fatal namespace errors though.

   I don't understand what it means. Libxml2 behaviour is the following:

laptop:~/XML -> cat tst.xml
<foo>
  <present:bar xmlns:present="http://example.com"/>
  <missing:bar/>
</foo>

laptop:~/XML -> xmllint --debug tst.xml
tst.xml:3: namespace error : Namespace prefix missing on bar is not defined
  <missing:bar/>
              ^
DOCUMENT
version=1.0
URL=tst.xml
standalone=true
  ELEMENT foo
    TEXT
      content=
    ELEMENT present:bar
      namespace present href=http://example.com
    TEXT
      content=
    ELEMENT bar
    TEXT
      content=

  seems the prefix part of the element name is missing, looks like a bug.
But libxml2 should not "invent" a namespace.
