In CSS terminology, 'normal' is usually associated with default
behavior.  It is *not* an assessment of what is "normal" in the general
sense of the world.

The term 'mixed-right' communicates *very* little, I don't think anyone
would understand what that means without looking up the definition.  And
by labeling it something other than 'normal' it's easy to miss that this
is the default behavior.

The problem with 'upright' in this context is that it's not really
"upright all the time", it's "upright most of the time but sometimes
not".  If sideways-xxx means that something is always displayed
sideways, some authors would assume that 'upright' is *always* upright.

As Florian noted during the F2F, if 'upright' is equivalent to "vertical
stacked" in Microsoft's proposal for UTR50 then there isn't currently a
value that is the complement to 'sideways'.
