+ * instance of this class either represents a permission

+ * particular service.  In the case of {@link MBeanPermission}s,
+ * implication checks are made using an instance of this class
+ * when a user requests an operation from the server, and a
+ * {@link SecurityManager} is in place.
+ * </p>
+ * <p>
+ * An {@link MBeanPermission} consists of four elements,
+ * which all have to match for the permission to be implied.
+ * These are as follows:
+ * </p>
+ * <ol>
+ * <li><strong>The action</strong>.  For a required permission,
+ * this is a single value.  For a permission held by the user,
+ * this is a list of comma-separated actions (with spaces allowed),
+ * or <code>*</code> (representing all actions).  {@link #getActions()}
+ * returns this value.</li>
+ * <li><strong>The class name</strong>.  For a required permission,
+ * this is the class name of the bean being accessed, if any.  If
+ * a bean isn't involved in this action, the value is <code>null</code>.
+ * For a permission held by the user, it has one of three values:
+ * <ol>
+ * <li>The empty string, implying any class.</li>
+ * <li><code>*</code>, also implying any class.</li>
+ * <li>A class name pattern, which may specify a single class
+ * (e.g. <code>java.lang.Object</code>) or a series of classes
+ * using the wildcard character <code>*</code> (e.g.
+ * <code>javax.swing.*</code>.)</li>
+ * </ol></li>
+ * <li><strong>The member</strong>.  For a required permission,
+ * this is the member of the bean being accessed (an attribute
+ * or operation), if any.  If a member of the bean isn't involved
+ * in this action, the value is <code>null</code>.
+ * For a permission held by the user, it has one of three values:
+ * <ol>
+ * <li>The empty string, implying any member.</li>
+ * <li><code>*</code>, also implying any member.</li>
+ * <li>The name of a member.</li>
+ * </ol></li>
+ * <li>The object name</strong>.  For a required permission,
+ * this is the {@link ObjectName} of the bean being accessed, if
+ * any.  If a bean isn't involved in this action, the value is
+ * <code>null</code>.  The name may not be a pattern.
+ * For a permission held by the user, it may be the empty
+ * string (allowing everything) or an {@link ObjectName}
+ * pattern.
+ * </li></ol>
+ * {@link #getName()} returns the latter three of these as a
+ * single string:
+ * </p>
+ * <p><code>className#member[objectName]</code></p>
+ * <p>
+ * where <code>""</code> is disallowed, as, although any of
+ * the elements may be omitted, not all of them should be
+ * left out simultaneously.  <code>"-"</code> is used to
+ * represent <code>null</code>.  When this occurs in a
+ * required permission, anything may match it.  When this
+ * forms part of a permission held by the user, it only
+ * matches another <code>null</code> value. 
+ * </p>
+ * <p>The list of valid actions is as follows:</p>
+ * <ul>
+ * <li>addNotificationListener</li>
+ * <li>getAttribute</li>
+ * <li>getClassLoader</li>

+ * management beans.  Patterns are distinguished from names by the
+ * presence of the '?' and '*' characters (which match a single
+ * character and a series of zero or more characters, respectively).
+ * </p>
+ * <p>
+ * Each name begins with a domain element, which is terminated by
+ * a ':' character.  The domain may be empty.  If so, it will be
+ * replaced by the default domain of the bean server in certain
+ * contexts.  The domain is a pattern, if it contains either '?'
+ * or '*'.  To avoid collisions, it is usual to use reverse
+ * DNS names for the domain, as in Java package and property names.
+ * </p>
+ * <p>
+ * Following the ':' character is a series of properties.  The list
+ * is separated by commas, and largely consists of unordered key-value
+ * pairs, separated by an equals sign ('=').  At most one element may
+ * be an asterisk ('*'), which turns the {@link ObjectName} instance
+ * into a <emph>property pattern</emph>.  In this situation, the pattern
+ * matches a name if the name contains at least those key-value pairs
+ * given and has the same domain.
+ * </p>
+ * <p>
+ * A <emph>key</emph> is a string of characters which doesn't include
+ * any of those used as delimiters or in patterns (':', '=', ',', '?'
+ * and '*').  Keys must be unique.
+ * </p>
+ * <p>
+ * A value may be <emph>quoted</emph> or <emph>unquoted</emph>.  Unquoted
+ * values obey the same rules as given for keys above.  Quoted values are
+ * surrounded by quotation marks ("), and use a backslash ('\') character
+ * to include quotes ('\"'), backslashes ('\\'), newlines ('\n'), and
+ * the pattern characters ('\?' and '\*').  The quotes and backslashes
+ * (after expansion) are considered part of the value.
+ * </p>
+ * <p>
+ * Spaces are maintained within the different parts of the name.  Thus,
+ * '<code>domain: key1 = value1 </code>' has a key ' key1 ' with value
+ * ' value1 '.  Newlines are disallowed, except where escaped in quoted
