• Clarified that defaults defined in components will be “promoted” to parameter defaults when used in command or event arguments

• Added defaults for various attributes, e.g. access, minEntries and maxEntries default to readOnly, 1 and 1 respectively
• Deprecated the mountType attribute’s none and mountable values, because mountable objects are now determined automatically

• Added previousCommand and previousEvent attributes
