Lab 1: Create a Compound Document

In this folder are three XML documents:

   - planets.xml
   - dc.xml
   - planets-plus-dc.xml

planets.xml contains a description of each planet in our solar system.
It conforms to the the XML Schema, planets.xsd

dc.xml contains metadata.  It uses the Dublin Core metadata elements.
It conforms to the Relax NG schema, dc.rng

Open each of these files, examine their content, and then validate them.
(I recommend using Oxygen XML to validate them because Oxygen supports 
both XML Schema validation as well as Relax NG validation)

planets-plus-dc.xml is a compound document.  The Dublin Core metadata has been 
inserted into the planets data.

You are to create an NVDL script for planets-plus-dc.xml
Name the NVDL script: planets-plus-dc.nvdl

After you have created the NVDL script, open a DOS window, change
directory (cd) to this folder, and then type: run

Remember: No News Is Good News!  If all you see after typing "run" is "Done" 
then there were no errors in your NVDL script.

Congratulations!  You've just written your first metaschema!
