For complex entity data types and multiple inheritance it is more complicated. Attributes order are as originally was written in EXPRESS file. For every instance there is four fields in one line. First one is the name of attribute, no operations on this field available. Second one is the type of attribute. The type writing is same as in EXPRESS. You can click on this type filed to see the detail of it. The third field is attribute value with plus and minus buttons for operations. For enumeration, logical and boolean types combo boxes with available values are shown instead of text field. If type of attribute is mixed select type (select are made not just from entity definitions) that beside attribute value combo box with available selections are placed. Second and third fields are separated with split, so you can enlarge attribute value view. With plus button you can set value from sdai clipboard for entity type and with minus button you can unset value for all attributes Fourth fieldis for showing is attribute set or not. If '$' mark is present at the endthen attribute is unset else attribute is set even if no value appear (set with empty string).
