Apart from the name of the attribute mistyped, I still see two problems with
your comment:
    - you lose the ability to "label" the open selection, which is useful in
    - I do not quite see how to handle the situation with more than one open
selection. The Recommendation requires multiplicity.

Asunto: RE: Select with open selection

I don't think the 1.0 Recommendation requires additional markup in the
choices or itemset to allow the presentation of a direct user-input area.
The only markup necessary is in the select element itself: <select
ref="my:flavors" enumeration="open">...</select>.
I do think that the attribute @enumeration should give your implementation
enough information to know to give the user a choice between the
choices/item and the direct user-input.  How your presentation chooses to
indicate that these are alternatives is up to you.  One mechanism common on
desktop/display/keyboard implementations is the "combo-box".
As an alternative to "combo-boxes," in the past couple of years, a more
flexible presentation has been used in some web sites: instead of using a
pull-down menu, these sites use a type-in field, and use the choices (or
itemset) to provide auto-completion, yet still allow alternate data to be
entered. In HTML4, this requires JavaScript, but in XForms, I believe that
it is just the @enumeration='open' attribute.
Please see my sample at
http://lists.w3.org/Archives/Public/www-forms/2006May/0122.html and think
about using it to present your select example below (though with
enumeration="open" and no empty value item).
There would be additional markup required in the form itself (events,
another instance, etc.) if you wanted to have the set of available choices
depend on what had been typed in the field so far and change incrementally,
but for your example with its static set of choices, just
@enumeration='open' should be enough.
Thank you,

Subject: Select with open selection



Xforms 1.0 Recommendation in Sections 8.1.10 and 8.1.11 states for
selection="open" that "Free entry text is handled the same as form control
input 8.1.2 The input Element, possibly in multiplicity."

IMO, id does not state clearly what the actual XML syntaxis is for this
situation and should be clarified. In our implementation we assume that an
empty value element means that the option is open, and then, treat it as an
input element for presentation.


For example, <select ref="my:flavors">
















                                    <label>Your choice</label>





would allow the user to enter "mango"
