Note that for a node to be treated as an ID in XSD 1.0, its typed value must be a *single* atomic value of type ID; the type of the node, however, can still allow a list.

getComponentAsFunction
public Function getComponentAsFunction()
Get the schema component in the form of a function item. This allows schema information to be made visible to XSLT or XQuery code. The function makes available the contents of the schema component as defined in the XSD specification. The function takes a string as argument representing a property name, and returns the corresponding property of the schema component. There is also a property "class" which returns the kind of schema component, for example "Attribute Declaration".- Specified by:
getComponentAsFunctionin interfaceSchemaComponent- Returns:
- the schema component represented as a function from property names to property values.
