In ยง 6.1 it is stated that the #profile feature MAY be used. I take this to mean that it is permitted to specify a ttp:profile attribute on the tt:tt element but not required. There's no suggestion of including the ttp:profile attribute within a document in a different location to what is defined in TTML1SE. Since the same principle of extension as in TTML1SE applies, it is also legal (but out of scope of the specification) to include the ebuttm:conformsToStandard element but strict processors can ignore it.
