[publican-list] Error: no ID for constraint linkend

[Michele Baldessari]

Hi all,

I am trying to get the docbook files contained in the Performance
Co-Pilot project [1] compiling on a recent publican version
(publican-4.2.6-0.fc21.noarch). After adding an <abstract>
section to Book_Info.xml and the missing Revision_History.xml/
Author_Group.xml files, I get the book compiling (only if I add
--novalid to the publican arguments though). 
In any case I get these "no ID constraint linkend" like the following:

To me these ID do exist and I cannot see anything all too
special about them. For example:
"""
<varlistentry>                  
<term><filename>${PCP_DIR}/etc/pcp.conf</filename></term>
<listitem><para><indexterm id="IG31371888122"><primary>${PCP_DIR}/etc/pcp.conf file</primary></indexterm>PCP    
configuration and environment file.</para>
</listitem></varlistentry>      
"""

Is there anything obvious I am missing, or are there some steps I should take
to troubleshoot this further? Feel free to clue me in as I have just started looking
at publican, I am complete newbie.

Thanks and regards,
Michele
