    -- as their initial portion. The common portion of the attribute holds
    -- the range to which the value in the type-specific part of the attribute
    -- applies and should be initialized using 'GI.Pango.Structs.Attribute.attributeInit'.
    -- By default an attribute will have an all-inclusive range of [0,@/G_MAXUINT/@].
