Lab 3: Lax Validation

In this folder is this XML document:

   - Library.xml

Open the document and inspect its content.

It is comprised of two different XML vocabularies:

   1. The Book XML vocabulary, which is specified
      by Book.rng

   2. The Employee XML vocabulary, which is specified
      by Employee.xsd

Also, Library.xml contains elements that are not declared
in either of the schemas.  When you validate the document, you want those
elements to be accepted.  That is, you want to do lax validation.

Write an NVDL script, Library.nvdl, which validates each Book
section against Book.rng, and each Employee section against
Employee.xsd, and accepts everything else. 

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.
