This package contains the classes and interfaces defined in the draft XQJ specification (JSR 225). This is designed as an interoperable API allowing applications access to XQuery implementations. The classes will eventually appear under the package `javax.xml.xquery`, but they are included in this package for the time being to reduce the risk of interoperability problems should the specifications change.

The package implements the Early Draft Review 2 edition of the specification published on 21 May 2007. This is available at http://jcp.org/aboutJava/communityprocess/edr/jsr225/index2.html. Note that this states that the specifications are subject to change and should not be considered in any way final. The interface specifications have been extracted from the published specification documents, and this process may have introduced errors.

The XQJ specification is Copyright (c) Oracle 2003, 2006, 2007.

The specification includes a license indicating the terms and conditions under which an implementation (a "derived work") may be produced and distributed. That license is to be considered as being incorporated into this implementation by reference. The license places requirements on implementations: this implementation meets those requirements except for requirement (d), which states that implementations must pass all compatibility tests. Saxon meets this requirement to the extent that there are at present no such tests.

The Saxon-specific classes that implement this interface are contained in package `net.sf.saxon.xqj`.
