I hope the following is conrete enough.

Imagine the following element:
 
<pi>3.14159265358979323846264338327950288419716939937510582097494459230781640628620899 
</pi>

(See http://www.joyofpi.com/pi.htm for details).

Suppose you are building a web services front-end to Macsyma (or 
Mathematica).  You might be tempted to add this attribute (assuming the 
"obvious" xmlns declarations)
	xsi:type=xsd:float

The problem is, that if you use something like DevStudio.Net and its 
wizards, you've guaranteed to have lost precision.  That's a shame, 
because the math tool has effectively infinite precision, but my 
XML/WS/XSD tool artificially limits itself to IEEE floats because it 
thinks it's doing me a favor by making it trivial to generalize object 
serialziation through XML.

Ok?
