Consider this example:

<!DOCTYPE foo [
<!ENTITY comment '<comment id="comment.xml" />'>
<foo xmlns="";>

When I run `xmllint --noout --noent --relaxng foo.rng foo.xml' I

| namespace warning : Namespace default prefix was not found
| ...
| element comment: Relax-NG validity error : Did not expect element comment there

But `jing foo.rng foo.xml' succeeds and does not complain. I have to add
the xmlns attribute to <comment> for xmllint to succeed. Is this correct
or an issue in xmllint? I wouldn't have expected, that I have to add the
namespace to this entity. I thought it gets directly replaced.

 libxml2 being designed as an editing toolkit, and before XML
namespaces does not handle well this kind of namespace and entities
mixups. Best is to add the namespace declaration in ten entity, yes.

We had the same issue for our ( and
documentations (written in Docbook5).
We use "shitloads" of entities for various things and "suddenly" got
thousends of "namespace default prefix was not found" errors as of
libxml2.7.4 (or was it .5 maybe?).

Although I do understand the logic be behind it (see bug#502960), it
caused us great deal of problems and not something I expected from a
bugfix release :|
To late to do anything about it now, long after the release :(
