Don't get me wrong, I am hugely in favour of embedding the GPD and Form info (not the forms themselves, althoughhh....) in the processdefinition. But I want them t o have their own namespace. But you probably also remember that.... btw... Tom is in favour, Koen is, only one person that is (was?) against this is Gavin (yes that one). But now for Seam they also thinking of embedding some seam related meta info about a page in the xhtml of the page and not in the pages.xml so.... who knows. About the DSL ;-) Google is your friend One of the blogs points to: http://www.martinfowler.com/bliki/DomainSpecificLanguage.html e.g. Drools/JBossRules has some things in this area where you can even create a DSL (although still rules related) Some other links: http://jspwiki.org/wiki/HowToImplementADomainSpecificLanguage http://www.infoq.com/news/domain-specific-language-debates (love this site!! one of my favourites, some nice discussions on WS-HELL) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092151#...
