Hi Nick,

I don't understand why you defined ValueTemplate thus:

        <xsd:complexType name="ValueTemplate" mixed="true">
                <xsd:attribute name="value" type="xforms:XPathExpression" 

I understand why you defined it (so you wouldn't have to write the same 
stuff over again), but this particular definition seems to allow the 
content of toggle/case, setfocus/control, load/resource, 
submission/resource to be other than character data.

mixed seems to allow a mixture of characters and elements, whereas we want 
the content of these elements to be use when there is no value attribute.

Wouldn't it be better to define it more like it is defined for the 
setvalue action, e.g. this:

                <xsd:complexType name="ValueTemplate">
                                <xsd:extension base="xsd:string">
                                        <xsd:attribute name="value" 
type="xforms:XPathExpression" use="optional"/>

I'm going to risk it and make the change to this latter form now, but 
please tell me whether or not this is a good idea...

Thank you,
