Title:  Add RemoveAttribute operation

Date Prepared:        March 29, 1996
Priority:             Routine
Document Affected:    Design (1.52)
Paragraphs Affected:  3.1
Reference:            none

Change Required:
  Add an operation to remove attributes from an Attributed Object

Specific Recommendation:
  Add the following operation to Abstract Class AttributedObject

  RemoveAttribute (AttributedObject, name: string)
    if AttributedObject has an Attribute whose Name component is
    name, remove that Attribute from AttributedObject (otherwise
    do nothing)

  [update Appendices B and C accordingly]

Reason for Proposed Change:
  This operation is needed to provide a complete set of operations
  for updating attributes.  This operation has been included in the
  NMSU Document Manager, but through oversight was not incorporated
  into the Design Document.

Applications Affected:
  Probably, none.  Applications already use this operation, as provided
  in the NMSU Document Manager.  This RFC brings the Design Document
  in line with current practice.
