Lab 1 - Fill in the XQuery

In this folder you will find planets.xml  Open it up to see its contents.
It contains data about planets. Note the default namespace declaration.

Also in this folder is planets.xq  Open it up to see its contents.
It is an XHTML document. We want to enrich it with data from planets.xml
You are to insert XQuery statements to retrieve the data. I've got a bunch
of UPPERCASE things in the document that instruct you on what data to retrieve.
Replace them with the appropriate XQuery.

After you're done and have it working, compare your planets.xq against 
planets.xsl, which is an XSLT implementation that does the same thing.
