sc:simple-type

sc:simple-type(
   [$arg as item()]
) as simple-type()?

Summary

Returns the simple type of item, as a schema component, if any. If the item has a complex type rather than a simple type, the empty sequence is returned. The context item is used if no argument is given.

• If the item is a document node, the result is the simple type of its root element.
• If the item is an element node, the result is the simple type of its element declaration.
• If the item is an attribute node, the result is the simple type of its attribute declaration.
• If the item is a schema component, the result is the associated simple type schema component.
• If the item is an atomic value, the result is the simple type of that atomic value.
• In other cases, the result is the empty sequence.
