Maven v3.0.3, PDF plugin v1.1 : fo:list-block is not a valid child element of fo:list-block

Hi,

I have an application using Maven1 for documentation currently, and wanted to 
upgrade to Maven3 in the (vain?) hope of getting the PDF plugin to work. The 
problem with the PDF plugin in Maven1 on this application is one of 
StackOverflowException in FOP due to the size of the docs. I've just migrated 
an amount of the docs for use in Maven3. I can get "site" to run (still to 
write a skin that lays it out as I want it), but when I run the PDF plugin I 
get

... (all files in XDOC format), validated and parsed ok.

Any ideas of what to try? Is this a bug in FOP, or the PDF plugin?

TIA

How did you validate the xdocs? When I run 'mvn -Dvalidate=true
site:site' on the project you attached at MPDF-57 I get stuck
immediately with basic validation errors (no schema definition). See
http://maven.apache.org/plugins/maven-site-plugin/faq.html#Can_I_validate_xml

Well I looked at it, but then since I'm not familiar with this FO format 
wouldn't know what is wrong with it. Since all XDOC files validated, then I'd 
assume the original file has no issue. Either way I have it in a separate 
project and is 100% reproduceable. Raised it as 
https://jira.codehaus.org/browse/MPDF-57



Thanks for your reply.

Did you look at the maven-pdf-plugin.fo file under target/pdf/ to see
what the fo file looks like? Seems like you ran into a bug, but I
don't know enough to say what caused it. If the fo file is wrong, then
either your original file has issues or whatever translated the
original into this fo file would seem to have an issue.
