Come on Tom.... Now I do not get you anymore... you opposed the addition of the variable type to the jdpl file so strongly and now in addition to a name, a mappedname and a description, a new label is added? Then please include the variable type as well, and now I come to think of it, why not include the coordinates as well (like xpdl) The name is to be unique (like an id) is, on transitions used, for reference (like an idref) why not ditch the name/to then and realy use an ID and idref? the xsd standard can make sure these constraints are automatically met (a refid should point to an existing id, id's should be unique etc..etc..etc..ebBP uses this) Sorry if I sound a little frustrated (two STFF posts in 10 minutes) but I do mean what I say View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008048#...
