+  Here is a quick overview of the main parts of this DTD.  For more information,
+  refer to the <a href="https://testng.org">main web site</a>.
+
+  A <b>suite</b> is made of <b>tests</b> and <b>parameters</b>.
+
+  A <b>test</b> is made of three parts:
+
+  <ul>
+  <li> <b>parameters</b>, which override the suite parameters
+  <li> <b>groups</b>, made of two parts
+  <li> <b>classes</b>, defining which classes are going to be part
+    of this test run
+  </ul>
+
+  In turn, <b>groups</b> are made of two parts:
+  <ul>
+  <li> Definitions, which allow you to group groups into
+    bigger groups
+  <li> Runs, which defines the groups that the methods
+    must belong to in order to be run during this test

+    @attr  name        The name of this suite (as it will appear in the reports)
+    @attr  verbose     How verbose the output on the console will be.
+                    This setting has no impact on the HTML reports.
+    @attr  parallel   Whether TestNG should use different threads
+                    to run your tests (might speed up the process)
+                    Do not use "true" and "false" values, they are now deprecated.
+    @attr  parent-module A module used to create the parent injector of all guice injectors used
+           in tests of the suite
+    @attr  guice-stage The stage with which the parent injector is created
+    @attr  configfailurepolicy  Whether to continue attempting Before/After
+                    Class/Methods after they've failed once or just skip remaining.
+    @attr  thread-count An integer giving the size of the thread pool to use
+                    if you set parallel.
+    @attr  annotations  If "javadoc", TestNG will look for
+                    JavaDoc annotations in your sources, otherwise it will
+                    use JDK5 annotations.
+    @attr  time-out     The time to wait in milliseconds before aborting the
+                    method (if parallel="methods") or the test (parallel="tests")
+    @attr  skipfailedinvocationcounts Whether to skip failed invocations.
+    @attr use-global-thread-pool - Whether TestNG should use a common thread pool
+    for running both regular and data driven tests in parallel. (Works only with TestNG versions 7.9.0 or higher)
+    @attr  data-provider-thread-count An integer giving the size of the thread pool to use
+           for parallel data providers.
+    @attr share-thread-pool-for-data-providers - Whether TestNG should use a common thread pool
+          for running parallel data providers. (Works only with TestNG versions 7.9.0 or higher)
+    @attr  object-factory A class that implements IObjectFactory that will be used to
+           instantiate the test objects.
+    @attr allow-return-values If true, tests that return a value will be run as well
