 === Dynamic Effects ===
+Dynamic effects are visual effects whose parameters are modified at runtime. A dynamic effect uses the <GetParameters> event on an <EventType> to dynamically set the effect parameters. For example:
+  <EffectType UNID="..."
+        instance="creator"
+        >
+     <Effect>
+        <Ray
+           style="..."
+           ...
+           >
+           <Events>
+              <GetParameters>
+                 (block Nil
+                    ...
+                    {
+                       length: ...
+                       width: ...
+                       intensity: ...
+                       }
+                    )
+              </GetParameters>
+           </Events>
+        </Ray>
+     </Effect>
+  </EffectType>
+In the above example, the parameters for the <Ray> effect are being set by the <GetParameters> function, which returns a struct. Each field in the struct represents a parameter in the <Ray> element to be set.
+The **instance** parameter on <EffectType> defines when <GetParameters> is called to set the effect parameters. The valid instances are:
+  * creator: The effect parameters are defined each time the effect is created (e.g., when the weapon is fired).
+  * game: The effect parameters are defined once at the beginning of the game and shared. For example, if multiple weapons use the same effect, all will use the same parameters.
+  * owner: The effect parameters are defined once per effect owner. For example, if multiple weapons use the same effect, the effect will be defined separately for each weapon.
+NOTE: As of API version 14, only the <Ray> effect supports dynamic effects.
