P1788 members: I have some difficulties with Section 3.1 of Draft 04.4: 3.1. Frequently used notation and abbreviations. In 3.1. of Draft 04.2 the set of closed and bounded real intervals is denoted by IR. Then it says: IF denotes the set of intervals of IR whose bounds are in F. This seems to me in accordance with the interval literature. "Classical interval analysis" deals with IR, sometimes also written as I(R). Also denotations like IRn, IRnxn, or IC (C stands for the complex numbers) are used. Do I understand it correctly that by Draft 04.4 in all these notations now the I has to be underlined? Why that? Also: 3.1. of Draft 04.2 says: \overline{IF} denotes the subset of \overline{IR} whose bounds are in F. By Draft 04.4 only the I is overlined? This looks strange to me. Can anybody give me an explanation? I may have misst something during the discussion? The notations of Draft 04.2 seem much more natural to me.
