confusing warning from xgettext about 'xml' extension being unknown

[Sandro Santilli]

This snippet:

  echo '<x> &undefined; </x>' > test.xml;
  xgettext test.xml

Results in this being printed on stderr:

  xgettext: cannot read test.xml: Entity 'undefined' not defined
  xgettext: cannot read test.xml: Entity 'undefined' not defined
  xgettext: warning: file 'test.xml' extension 'xml' is unknown; will try C

I find it confusing, because the 'xml' extension is clearly known or
otherwise xgettext would not even try to resolve the entity, right ?
