Notes about XML Events 2 W3C Working Draft 16 February 2007

All,

Please consider the comments below on "XML Events 2 W3C Working Draft
16 February 2007" [1]:

1. event() function's return type
---------------------------------

In [1], event() returns a node-set. In XForms 1.1 CR, event() returns
an object [2]. Practically, it can return at runtime node-set, string,
and number objects.

Please make this consistent with XForms 1.1 by allowing a return type
of object.

2. Ability to register multiple events with the @event attribute
----------------------------------------------------------------

It is often useful to register the same handler for multiple
events. The @event attribute is defined as a QName, therefore not
including spaces.

My request is to extend the content of the @event attribute to support
a space-separated list of QName, with the meaning of listening to more
than one event type.

Example with XForms:

<xforms:action ev:event="xforms-valid xforms-invalid">
   ...

3. Ability to register multiple  observers with the @observer attribute
-----------------------------------------------------------------------

Similarly, it is useful to attach a handler to multiple observers.

My request is to extend the content of the @observer attribute to
support a space-separated list of IDREF, with the meaning of attaching
the handler as an observer to more than one location.

Example with XForms:

<xforms:action ev:event="xforms-value-changed" ev:observer="trigger1  
trigger2">
   ...

4. Ability to register multiple targets with the @targetid attribute
--------------------------------------------------------------------

Similarly, it is useful to specify a match for multiple targets.

My request is to extend the content of the @ targetid attribute to
support a space-separated list of IDREF, with the meaning of checking
on more than one target.

Example with XForms:

<xforms:action ev:event="xforms-value-changed" ev:targetid="trigger1  
trigger2">
   ...

Best,

-Erik
