the specification talk about complex types and simple types
i was talking about simple types ; a raw data is "12345" or "2005-06-01"

I agree that XML Schema is not the place to define an xml:element type
but I complain about XPath2, that need such a type but uses something
else than a qualified name

the infoset could define this types

But what would be the point of adding information to an element to say
that it is an element? Or are you trying to do something else?
i try to qualify types with QNames :
xs:string for a string
xs:int for an int
xml:element would be fine for an element
my:order for an order, not necessarily unmarshalled from an XML
document, but it could

i was enlightening the fact that element() sounds like a function, not a
type name !
i really prefer xml:element
