> This sample illustrates how you can use the XMLBeans API to execute
> XPath and XQuery expressions. The sample illustrates these features:
> - Using the XmlObject.selectPath and XmlCursor.selectPath methods
> to execute XPath expressions. The selectPath method's results (if
> any) are always chunks of the instance queried against. In other
> words, changes to query results change the original instance.
> However, you work with results differently depending on whether
> selectPath was called from an XmlObject or XmlCursor instance. See
> the SelectPath class for more information.
> - Using the XmlObject.execQuery and XmlCursor.execQuery methods
> to execute XQuery expressions. Results of these queries are copied
> into new XML, meaning that changes to results do not change the 
> original instance. Here again, you work with results differently
> depending how which method you used to query. See the ExecQuery
> class for more information.
> A note about dependencies. Very simple XPath expressions -- e.g.,
> expressions without predicates or function calls -- require only
> the xbean.jar on your class path. More complex expressions require
> xbean_xpath.jar. XQuery expressions require the Saxon 8.1.1 JAR. 
> Both xbean_xpath.jar and saxon8.jar are created for you when you build
> XMLBeans from Apache source code. These files are required on the class
> path for code in this sample to run.
> To try out this sample:
> 1. Set XMLBEANS_HOME in your environment
> 2. Ant must be on your PATH
> 3. xbean_xpath.jar and saxon8.jar must be on your class path.
>    These files are created in the build/lib directory when you 
>    build XMLBeans from source.
> 4. To compile the schemas and sample source, run "ant build"
> 5. To execute the sample, run "ant run"
