Re: Agenda

All,

Apologies, but due to work being exceedingly tight on the run-up to the end of March I will not be able to attend any Working Group calls until April.


Regards

Philip

Mostly LGTM.

Do we need to capitalize "Action" as in "on Actions and […]"?
This has been inherited from XForms 1.1; we could agree to decapitalise the uses.


One thing that is missing is what happens if an expression requests a typed value and the value cannot be converted to that type. For example, say the element content is empty but has type `xs:time`.

Our implementation throws a runtime error when that happens. Another possibility could be to return the empty sequence.
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?

I'm about to send the agenda, but I'd like to draw attention to the
request to PLEASE read Sections 6.1 and 6.2 in Expressions

I have rewritten it to be more readable, and it shouldn't have changed any
meaning. Please check you agree.

Thanks!
