  http://ww
w.w3.org/TR/REC-xml/#NT-ExternalID
  [Definition: The SystemLiteral is called the entity's
system identifier. It is meant to be converted to a URI
reference (as defined in [IETF RFC 2396], updated by [IETF
RFC 2732]), as part of the process of dereferencing it to
obtain input for the XML processor to construct the
entity's replacement text.]

  "relative URIs are relative to the location of the
resource within which the entity declaration occurs"

  that's what drives libxml2 behaviour.

 like any other error in libxml2, which I think I answer on
an average of
2 times a weeks those days,
