+ * Represents attribute name/value pairs from a Manifest as a Map.
+ * The names of an attribute are represented by the
+ * <code>Attributes.Name</code> class and should confirm to the restrictions
+ * described in that class. Note that the Map interface that Attributes
+ * implements allows you to put names and values into the attribute that don't
+ * follow these restriction (and are not really Atrribute.Names, but if you do
+ * that it might cause undefined behaviour later).
+ * <p>
+ * If you use the constants defined in the inner class Name then you can be
+ * sure that you always access the right attribute names. This makes
+ * manipulating the Attributes more or less type safe.
+ * <p>
+ * Most of the methods are wrappers to implement the Map interface. The really
+ * useful and often used methods are <code>getValue(Name)</code> and
+ * <code>getValue(String)</code>. If you actually want to set attributes you
+ * may want to use the <code>putValue(String, String)</code> method
+ * (sorry there is no public type safe <code>putValue(Name, String)</code>
+ * method).
