XName | An Expanded Name, consisting of a (optional) namespace name and a local name.

## Package com.marklogic.xcc.types Description

### XCC Type Definitions.

This package contains classes that map XML Data Model (XDM) data types to Java types. There are two roughly parallel class hierachies in this package: those which correspond to an XDM value instance (for example: `XSDecimal`) and those which describe an XQuery type (for example `AtomicType`).

The descriptive types, those whose name ends in "Type", constitute a type-safe enumeration. These classes may not be instantiated by user code. The class `ValueType` defines the public, immutable instances of all the available type descriptive classes. And the static class method `ItemType.forType(String)` provides a convenience mapping from XQuery type names to the corresponding descriptive class.

The class hierarchies of the type classes are shown in these UML diagrams. Click on the images to see them full-size:
