Should I go ahead with above modified function name or modify it to
ariaRoleHasNoneChildren?

Since presentation would be deprecated.

[dmazzoni, 2014/09/22 06:12:23]

My vote is to leave it alone - ariaRoleHasPresentationalChildren - the word
"presentational" can just mean has role="presentation" or role="none".
