Where are XML types ?

Where are XML types ?
People know xs:string, xs:int and xs:QName, because they are taken from 
raw data, but is there high level types for XML items such as 
xml:element, xml:attribute, or xml:namespace ?
I have to name (with a QName) objects (that can be XML items) as if they 
were types.
I really really don't think that XPath2 offers a reasonable solution with :
"5 instance of xs:integer"
". instance of element()"
the last one frightened me :(

Where is the xml:element type ?
