"Nick: I will be away the first three weeks of September"
<nvdbleek> zaki, code?
http://lists.w3.org/Archives/Public/public-forms/2013Aug/0005.html
Erik: People have trouble working
out how to do this. It is hard in many languages.
... handling currencies for instance should be in decimal
http://blog.orbeon.com/2013/08/orbeon-forms-43.html
Steven: Anything particular worth mentioning?
Erik: Extensions that might be
worth bringing to XForms sometime
... dealing with multiple constraints
... different alert messages for different constraints
... and BetterForms have something similar
... we went a little further
... and have warnings as well as errors

Steven: For the record

Steven: Advertising the benefits of AVTs in XForms

Steven: An interesting analysis, not sure how true.
http://lists.w3.org/Archives/Public/public-forms/2013Aug/0009.html
Steven: Looked fine to me
... everyone else OK?
Erik: We had discussed
earlier
... John Boyer had said "it would be nice if..." with some
extra features, but they aren't in there.
... issues with the dependency graph.
... Would need more work to deal with that.
information to the nodes in instances
http://lists.w3.org/Archives/Public/public-forms/2013Aug/0007.html
Nick: We never came to a conclusion with this. It sort of fizzled out.
Erik: I had it on my list, I
realised recently looking at the expressions (see above), that
it needed to be done.
... the problem is that any expression that deals with data in
the model, involves types.
... numbers and dates particularly
... it makes perfect sense that expressions use information
about the types without using casts
Steven: So you derive types from the model and pass them on?
Erik: XPath engines can support
this.
... Xpath 2 supports using type information (e.g. in a+b) if
available.
Steven: Is it as if you are supplying invisible casts?
Erik: Yes.
... Xpath 2 supports it in the API
... I had an action item to ask Mike Kay
... XForms can't guarantee that at runtime the value has the
right type.
... Mike Kay was a bit puzzled, and was surprised about what I
told him, probably because he is not at home with XForms
... but he said he would expect an implementation would provide
types
Steven: So you proposed writing some text.
Erik: Yes. I don't think it is
too hard to specify.
... Kay suggested that the results of the calculations should
be used for coercions.
... I haven't considered that yet.
Nick: If you have a bind to a
schema type, some Xpath engines don't necessarily support
it.
... so it can't be required.
Erik: Right.
... but having support for the simple types is already
useful.
Nick: I agree.
<scribe> ACTION: Erik to write text for type information for XPath expressions [recorded in http://www.w3.org/2013/08/21-forms-minutes.html#action01]
<trackbot> Created ACTION-1955 - Write text for type information for xpath expressions [on Erik Bruchez - due 2013-08-28].
Steven: Nick is about to go away.
I shall be unavailable for two calls.
... So let's try for a call for the 18th September, but up to
then we are on hold.
Nick: I won't be able to do preparatory work for that call.
Steven: No problem, we can use the call to schedule the progress.
Steven: ?
