Personally I avoid mixed content models wherever possible. So it is more of an issue for those that don't.

I was just messing about with these functions to see whether they were robust with respect to stability (that is stability as in a stable sort).
[DAL:] ==============

Even neglecting mixed content ( dont use that for data !) 
... functions that expect atomics or lists of atomics generally dont do what you want when you give it *nested* XML.

sum( <a><b>1</b><c>2</c></a> )  == 12

Its nice enough to try to simple content elements but not nested ("complex") elements.

You *do* have to be careful with this.  I wouldnt classify it as "stability" but its a rational argument.
Dont be putting stuff in functions that you dont know whats in there ... and expect to get something out that you expect.
