=head1 NAME

Bugzilla::Testopia::XmlTestCase - Testopia XmlTestCase object

=head1 DESCRIPTION

This module parsers a XML representation of a Testopia test plan,
test case, test environment, category or build and returns Testopia
objects re

# The XmlTestCase structure stores data for the verfication processing.  The database is not updated
# until a verfication pass is made through the XML data.  Some of the TestCase class references are
# database references that will not be valid until the class has been stored in the database.  This
# structure stores these references to be used during verfication and writting to the database.
