Comment (by jauecker):

 '''Chris:'''



 >We don't say that you can only use the <int/> operator with integrable
 functions,

 Sure, but for K-12 it would be reasonable to limit to a smaller,
 understandable class of functions (assuming we said anything at all
 about their domains, such as what a funtion is and whether it is real,
 complex, quarternionic ...).  For example we could only integrate
 functions with 'discrete discontinuities' (thus nothing on 'bounded
 variation' ... hope I recalled that bit correctly:-).


 >MathMl spec doesn't need to take a view does it?

 Can I reiterate: my examples are not there to argue for a particular
 wording!

 So no, a view is not needed, from the viewpoint of a formal specification.

 But all the time I see the current spec taking such views, often
 implicitly.

 For example:
 The current stuff is permeated through and through with 'the view'
 that there are some magic beasts lurking around that I would call
 'elements of a (dense subset of a) real field', which may possibly be
 'the Reals' (assuming they are unique:-) but with hints sometimes that
 'the view' is of something (mathematically) totally different such as
 'the IEEE reals': but we are never told about what beasties have been
 blessed, or why!
