+%    2. The overall rule is that symbols representing physical quantities (or
+%       variables) are italic, but symbols representing units, or labels, are
+%       roman. [...]
+% 
+%    3. The above rule **applies equally to letter symbols from both the Greek
+%       and the Latin alphabet**, although authors often appear to resist
+%       putting Greek letters into italic.

+% [emphasis by the author]. In contrast, the standard LaTeX style treats Greek
+% symbols as invariant operators with lower case italic and upper case upright.

+% Attention: Some fonts (CM, Latin Modern, ...) have old-style figures in
+% their math italic version. The Null vector must not be written ``\vec{0}``
+% in this case. Use e.g. ``\mathbf{0}``, ``\boldsymbol{0}`` (with AMS math) or
+% ``\bm{0}`` (with boldmath). The latter two variants provide also a failsafe
+% alias for a bold vector.
