I have just added a little grammar of GACL to room.xtext file in ord.etric.core.room project. It is just to allow the code declaration in GACL syntax along inside DetailCode. Its fully backward compatible. I just uploaded the commit using gerrit for first time. So please do review it without subject also i will be commiting another code fully working and fully backward compatible soon with changes in code generator or converter you may say. If someone can tell me how to give topic name / subject to review requests coming through gerrit please do tell. I am using Egit with gerrit configured.
