    Yes, it is. The issue is rather to understand what to do when the 
renderer can not display some combination of known values (for instance, 
MathPlayer ignores "circle" when is used with "radical" but other 
renderers can behave differently). But I don't think these rules should 
be indicated in the spec.

    The only examples of combined values is "circle horizontalstrike" or 
"top right" and it is clear that they can't be nested. The issue appears 
when you want to implement something like "circle box" (see screenshot). 
There is no explicit statement about how to deal with this case.
