I'm not sure what you mean. Clearly the DOM specifications need to say
how the abstract interfaces map to ECMA-262 language concepts, and for
the specific issue at hand, if .onfoo attributes are Function objects,
Function.prototype.toString() is quite relevant: Function.prototype.toString()

    An implementation-dependent representation of the function
    is returned. This representation has the syntax of a
    FunctionDeclaration. Note in particular that the use and
    placement of white space, line terminators, and semicolons
    within the representation string is implementation-dependent.
    The toString function is not generic; it throws a TypeError
    exception if its this value is not a Function object.
    Therefore,  it cannot be transferred to other kinds of objects
    for use as a method.
