This has been inherited from XForms 1.1; we could agree to decapitalise  
the uses.

The text says:

"If the evaluation of an expression fails:
  * for a calculate expression, the result is the empty sequence;
  * for other bind computed expressions (which are all boolean valued), the  
result is the opposite of the default for that property;
  * for all other expressions, an xforms-expression-error event is  
dispatched to the element containing the expression."

Does that not cover it?
