Hello all,

Consider the following DocBook 5 files:

test.xml
========


%testent;
]>
<book xmlns="http://docbook.org/ns/docbook" version="5.0">

<info>

<subtitle><orgname>&company;</orgname></subtitle>
<author>
<personname>
<firstname>John</firstname><surname>Brown</surname>
</personname>
</author>
<copyright>
<year>2008</year><holder>&company;</holder>
</copyright>
</info>

&test1;



</book>


test.ent
========



test1.xml
=========
<chapter>
<para>OK</para>
</chapter>

When I run 'xmllint --noout --relaxng /path/to/docbook.rng test.xml',
it returns:
test.xml:1: element chapter: Relax-NG validity error : Did not expect element
chapter there
test.xml:1: element chapter: Relax-NG validity error : Element book failed to
validate content
test.xml fails to validate

If I comment out "&test1;" and uncomment the chapter definition, then
test.xml validates.

What am I doing wrong?

Unfortunately, I experienced also some problems with xmllint in regard to
DocBook5 validation. I would suggest to try another validator, for
example jing or msv. See the following link for more information:

By the way: You can also use XInclude instead of external entities. This
technique is also described in the above document.
