so, are the above syntaxes both
correct when using class or cssclass,
because they don't seem to be.
I am not sure what you mean when you say they do not "seem" to be correct? Do they render differently, even when you are using
in both cases?
IMHO, as far as the 'class' attribute is concerned, they are both correct. Did you try .someClass > th instead of .someClass th in the second case? That might solve the problem.
