+ *     The filter can be used only to suppress audit events received from

+ *     SuppressWithPlainTextCommentFilter knows nothing about AST,
+ *     it treats only plain text comments and extracts the information required for suppression from
+ *     the plain text comments. Currently the filter supports only single line comments.
+ * </p>
+ * <p>
+ *     Rationale:
+ *     Sometimes there are legitimate reasons for violating a check. When
+ *     this is a matter of the code in question and not personal
+ *     preference, the best place to override the policy is in the code
+ *     itself.  Semi-structured comments can be associated with the check.
+ *     This is sometimes superior to a separate suppressions file, which
+ *     must be kept up-to-date as the source file is edited.

+              <p>
+                  Filter <code>SuppressWithPlainTextCommentFilter</code> uses plain text to suppress
+                  audit events. The filter can be used only to suppress audit events received from
+                  the checks which implement FileSetCheck interface. In other words, the checks
+                  which have Checker as a parent module. The filter knows nothing about AST,
+                  it treats only plain text comments and extracts the information required
+                  for suppression from the plain text comments. Currently the filter supports
+                  only single line comments.
+              </p>
+              <p>
+                  Please, be aware of the fact that, it is not recommended to use the filter
+                  for Java code anymore, however you still are able to use it to suppress audit
+                  events received from the checks which implement FileSetCheck interface.
+              </p>
+              <p>
+                  Rationale: Sometimes there are legitimate reasons for violating
+                  a check.  When this is a matter of the code in question and not
+                  personal preference, the best place to override the policy is in
+                  the code itself.  Semi-structured comments can be associated
+                  with the check.  This is sometimes superior to a separate
+                  suppressions file, which must be kept up-to-date as the source
+                  file is edited.
+              </p>
+              <p>
+                  Note that the suppression comment should be put before the violation. You can use more
+                  than one suppression comment each on separate line.

     <section name="What is Javadoc comment">
       <p>
-      Javadoc comment is multiline comment <code>/*  */</code> that starts with <b>*</b> character and placed above class definition, interface definition, enum definition, method definition or field definition.
+      Javadoc comment is a multiline comment <code>/*  */</code> that starts with the <b>*</b>
+      character and placed above the class definition, interface definition, enum definition,
+      method definition or field definition.
+      If an annotation precedes any of the definitions listed above, then the javadoc comment
+      should be placed before the annotation.
+      If several multiline comments with javadoc identifiers are placed sequentially, only
+      the one closest to the definition, right above it, with the javadoc identifier will be used.
+      </p>
+      <p>
+      Javadoc comments should contain: a short summary (the first sentence), an optional
+      documentation section, an optional tag section.
+      The first sentence has a special meaning and should be clear, punchy, short, and is ended by
+      a period symbol.
+      Immediately after the first sentence, the main description could begin, which may be followed
+      by the tag section.
+      The tag section starts with the first block tag, which is defined by the first <code>@</code>
+      character that begins a line (ignoring leading asterisks, white space, and leading separator
+      <code>/**</code>).
+      </p>
       <p>For example, here is java file:</p>
       <source><![CDATA[
 /**
  * My <b>class</b>.
- * @see AbstractClass
+ *
+ * @see Annotation
  */
 public class MyClass {
 
+  /** Not a javadoc (ignored). */
+
+  /**
+   * Doubles the value.
+   * The long and detailed explanation what the method does.
+   *
+   * @param value for doubling.
+   * @return double value.
+   */
+
+  /*
+   Multiline comment (ignored).
+  */
+  @Annotation
+  /** Extra javadoc (ignored). */
+  // Single line comment (ignored).
+  public int method(int value) {
+    /** Inner javadoc (ignored). */
+    return value * 2;
+  }
 }
       ]]></source>
-      Javadoc content is:
+      <p>Javadoc content for the MyClass will be:</p>
       <source><![CDATA[
- * My <b>class</b>.
- * @see AbstractClass
+    My <b>class</b>.
+
+    @see Annotation
       ]]></source>
-      </p>
+      <p>Javadoc content for the MyClass.method will be:</p>

+    The long and detailed explanation what the method does.
+
+    @param value for doubling.
+    @return double value.
+      ]]></source>
+      <p>
       Attention that java comment starts with <code>/*</code>, following with Identificator of comment type. Javadoc Identificator is <code>*</code>. All symbols after Javadoc Identificator till <code>*/</code> are part of javadoc comment.
