Details
This function takes an item as argument.
If the argument is an element or attribute node, the function returns the type annotation of the node, as a QName. If the type is anonymous, this will be a system-generated internal name.
If the argument is a document node, the function returns xs:anyType
if the
document has been schema-validated, or xs:untyped
otherwise.
For a text node, the function returns xs:untypedAtomic
, and for comment,
processing-instruction, and namespace nodes, it returns xs:string
.
If the argument is an atomic value, the function returns the type label of the atomic value, again as a QName.
If the argument is an empty sequence, the function returns an empty sequence.
The prefix of the returned QName should not be treated as significant.
