Could you describe in more detail what you would like to do? Are you
saying that this is something you cannot do with <xxforms:script>?
(See below for reference to the documentation of <xxforms:script>.)

There is a xxforms:xforms-dialog example segment:

<html>
<head>

<xforms:model>
            
            <xxforms:dialog-submission id="dialog-submission-1" level="model"
                   ref="instance('**')" instance="**" action="/**" />
        </xforms:model>
</head>
<body>
      <xforms:trigger>
          <xforms:label>Open Model Dialog</xforms:label>
          <xforms:action ev:event="DOMActitave">
              <xxforms:xforms-dialog dialog-submission="dialog-submision-1"/>
          </xforms:action>
      </xforms:trigger>
</body>
</html>

<html>
<head>
</head>
<body>
      <xforms:trigger>
           <xforms:label>OK</xforms:label>
           <xforms:action ev:event="DOMActitave">
               <xxforms:xforms-dialog-close type="ok" ref="instance('**')/**"/>
           </xforms:action>
      </xforms:trigger>

      <xforms:trigger>
         <xforms:label>Cancel</xforms:label>
         <xforms:action ev:event="DOMActitave">
             <xxforms:xforms-dialog-close type="cancel"/>
         </xforms:action>
      </xforms:trigger>
</body>
</html>

你好！

Well, in general you don't create new actions in XForms: a set of
standard actions is specified by the XForms spec, and a few extension
actions have been defined in Orbeon Forms because they have no
equivalent in the XForms spec (like xxforms:script). The philosophy of
XForms actions is that you can combine them together without creating
new ones.

Inventing new actions would require you to modify the Orbeon Forms
XForms engine. Orbeon Forms is open source so of course you are free to
modify it. But there should be a very, very good reason to invent a new
action ;-) Anyway if you really want to do this, the source code is your
friend: we don't have specific documentation on how to add new custom
actions to the XForms engine.

By the way, in your example below, you invent a new element,
xxforms:dialog-submission in the model. A regular xforms:submission
element would probably just do.

But it looks like the functionality you are looking for is to implement
some sort of communication between a parent form and a child dialog
defined in another page. So we should start by trying to figure out what
the best design for that would be. At this point, I am not sure!
