=== Changes in XML elements between 0.99c and 1.0 RC1 ===

FIXME This is *very* rough draft. Please contribute.

  * Two new system events (can be used with objRegisterForSystemEvents)
    * OnSystemWeaponFire
      * aWeaponObj  -  the ship firing the weapon
      * aWeaponUNID -  unid of the weapon being fired
    * OnSystemExplosion

  * three new OnDamage* events
    * Seems like they are used on the items causing the damage
      * OnDamageShields  -  the damage returned is the damage applied
        * aDeviceItem  - The device being damaged
        * aDamageHP  -  The initial damage rolled
      * OnDamageArmor  -  the damage returned is the damage applied
        * aHitPos  -  position of hit
        * aDamageHP  -  initial damage
        * aHitDir  -  direction of hit
      * OnDamageOverlay  -  Would seem to have the same vars as the others
  
  * onObjUpdate: needs to be tested, probably only works on space enviroment types
    * provides aObj

  * New AI attribute aggressor="true/false"
  * New attribute in the Relationship tag, mutual='true/false'

  * Ship tags inside of <Ships> elements can now contain a <Names> tag
  * Ships can now inherit from a base ship class, using the inherit attribute

  * OnDamage provides a aWeaponType variable (weapon UNID)

  * New <OverlayType> element (which seems to be quite complex) works with objAddOverlay function.

  * New attribute on items, useKey which can assign a key to a usable item, even if it has a screen associated with it (using the useScreen attribute)
    * This probably means the <Invoke> block has changed
  * ItemType attribute: useInstalledOnly/unInstalledOnly.

  * <Names> has new attribute personalName='true/false'
  * <Action> elements have a nextKey='1' and a prevKey="1" attribute. Wonder what that does.

  * The <Canvas> element is quite a mouthful - works with canvas functions.
    * attributes: left, top, right, bottom

  * <EnhancerDevice> has been completely revamped. In particular the new attribute "criteria" that gives extreme flexibility in enhancing items.
  * <Relationships> is a new child for <Sovereign>, where it's possible to specify the disposition of other sovereign.
