functx:id-untyped

Gets XML element(s) that have an attribute with a particular value

Description

The functx:id-untyped function simulates the built-in fn:id function except that the value specified can be the value of any attribute, not just one declared to be of type xs:ID. This is useful for getting elements based on ID when a schema is not present. It returns all elements that have any attribute, regardless of name, whose value is the specified value.
