in current project, developing domain specific language. instance, syntax of language following:

structs:      tempstruct          tempvalue : double;          unitofmeasurement : string;          abilities:     sensors:          temperaturesensor               attribute responseformat : string;              generate  tempmeasurement : tempstruct; // forward reference of defined structs

in above code fragment, can see tempstruct defined. requirement want facilitate dsl programmers drop down list of defined structure. so, programmer can select 1 structs drop down list.
