One model, many instances, is it correct?

Hello, heve a look at this piece of code:

<head>
	<title>Greenhouse Catalog Data Entry</title>
	<link   rel="stylesheet" type="text/css" href="greendb.css"/>
  	<xf:model id="model1">
    	<xf:instance src="dbview.xml" id="dbview" ></xf:instance>
	<xf:instance src="session.xml" id="session" ></xf:instance>
	<xf:instance src="workarea.xml" id="wka" ></xf:instance>
	<xf:bind nodeset="/wka/full_name"
calculate='concat(/dbview/genus_name,"aaa ",/dbview/species_name)'/>
	<xf:bind id="msg"  nodeset="/wka/message" />
	<xf:submission  id="squery" ref="instance('dbview')"
method="form-data-post" action="query.php"/>
        <xf:submission  id="sinsert" ref="instance('dbview')"
method="put" replace="none" includenamespaceprefixes="#default"
action="submit.xml"/>
	</xf:model>
</head>

I read specs carefully, nowhere this is forbidden, will it be supported
?
For one instance all works fine, for many those beyond the first become
"mute"
but no error messages. Can I plan the code this way ? (Note the
"calculate" among nodes of different instances)

Using Xforms preview 2 etc...

thanks
