This represents a sequence of ASN.1 objects,
 where ASN.1 is "Abstract Syntax Notation number One".

 Overview of how this ASN1 interface is intended to
 work.

 First off, the nsIASN1Sequence is any type in ASN1
 that consists of sub-elements (ie SEQUENCE, SET)
 nsIASN1Printable Items are all the other types that
 can be viewed by themselves without interpreting further.
 Examples would include INTEGER, UTF-8 STRING, OID.
 These are not intended to directly reflect the numberous
 types that exist in ASN1, but merely an interface to ease
 producing a tree display the ASN1 structure of any DER
 object.

 The additional state information carried in this interface
 makes it fit for being used as the data structure
 when working with visual reprenstation of ASN.1 objects
 in a human user interface, like in a tree widget
 where open/close state of nodes must be remembered.

Attributes

  The array of objects stored in the sequence.
attribute nsIMutableArray ASN1Objects 
  Whether the contained objects should be shown or hidden.
  A UI implementation can use this flag to store the current
  expansion state when shown in a tree widget.
attribute boolean isExpanded 
  Whether the node at this position in the ASN.1 data structure
  sequence contains sub elements understood by the
  application.
attribute boolean isValidContainer
