I asked for --noent in the first example above, but not in the second.
 As noted, 'xmllint --noout <filename>' without --noent gives the same
behavior.  I probably should have made the two examples more distinct
visually.

Is the above behavior (without --noent) a bug?  If so, I'll gladly
file a bug report.
