Hi Patrick,

More test scripts are always welcome. Thanks for taking this up. What 
kind of tests are you considering to cover?

Creating a rendering class like $xhtml is a good suggestion, and we can 
also think about all other classes that current have rendering function 
that generates xhtml from the core, for example,

*search result page and search form
*Input components, e.g. Plugin/InputForm/Component/Field/Multi.pm
*how would the screen plugins work?
*Metafields, e.g. Metafield/Compound.pm etc
*How does this affect multi language renderings, e.g. Language.pm

It would be ideal if we can render everything using this rendering class.

The primary focus of the next version of eprints (3.4) is to move 
repository type related code out of the core, so that the core is 
smaller, and the code that is only related to a publication repository 
stays in a package (we may call it flavour). This way, we can build 
other types(flavours) of repositories, e.g. data-repository, education 
resource repository(edshare) and micro-repositories more cleanly and 
easier to manage. This is also a step towards a generic core that is not 
based on publication.

Best
Jiadi
