    I think what I last sent was to Michael and Don only, so 
    here is a restatement to the group and to get archived.
    
    Graphic image sizing changes require modifications
    to two areas:  the image element and the object element
    in the language reference. 
    
    I am suggesting we don't change the scale attribute 
    in %display-atts, since that is mostly about scaling
    text.  (However, we might correct "accomodation" to be
    "accommodation" in the Description of the scale attribute.)
    
    I am not suggesting we add the scale attribute to the
    object element at this time (though I wouldn't be opposed
    if the TC felt that made more sense).
    
    No changes are needed in the Architectural Specification.
    
    The image element
    =================

    first para
    ----------
    Replace:
    
     The <image> element has optional attributes that indicate
     whether the placement of the included graphic or artwork
     should be inline (like a button or icon), or on a separate
     line for a larger image. 
    
    with:
    
     The <image> element has optional attributes that indicate
     whether the placement of the included graphic or artwork
     should be inline (like a button or icon) or on a separate
     line for a larger image.  There are also optional attributes
     that indicate the size to which the included graphic or artwork
     should be scaled.
    
    (That is, remove the bogus comma in the existing sentence
    and add the additional sentence.)
    
    under Attributes
    ----------------
    Replace the height attribute's description with:
    
     Indicates the vertical dimension for the resulting image
     display. If necessary, the image is scaled to the specified
     size. The value of this attribute is a real number optionally
     following by a unit of measure from the set of pc, pt, px, in,
     cm, mm, em (picas, points, pixels, inches, centimeters,
     millimeters, and ems respectively).  The default unit is px
     (pixels). Possible values include: "5", "5in", and "10.5cm".
     If a height value is specified and no width value is specified,
     the width will be scaled by the same factor as the height.
     If both a height value and width value are specified, some
     implementations may not be able to scale the two directions
     by a different factor and may therefore ignore one of the
     two values.
    
    
    Replace the width attribute's description with:
    
     Indicates the horizontal dimension for the resulting image
     display. If necessary, the image is scaled to the specified
     size. The value of this attribute is a real number optionally
     following by a unit of measure from the set of pc, pt, px, in,
     cm, mm, em (picas, points, pixels, inches, centimeters,
     millimeters, and ems respectively).  The default unit is px
     (pixels). Possible values include: "5", "5in", and "10.5cm".
     If a width value is specified and no height value is specified,
     the height will be scaled by the same factor as the width.
     If both a height value and width value are specified, some
     implementations may not be able to scale the two directions
     by a different factor and may therefore ignore one of the
     two values.
    
    
    Add the "scale" attribute to the attribute list:
    
     Description:  Specifies a percentage by which to scale the
      image in the absence of any specified image height or
      width; a value of 100 implies that the image should be
      presented at its intrinsic size.  If a value has been
      specified for this image's height or width attribute
      (or both), the scale attribute is ignored.
    
     Data Type:  NMTOKEN whose value space is an unsigned integer
    
     Value:  #IMPLIED
    
     Required?:  No

    The object element
    ==================
    http://docs.oasis-open.org/dita/v1.0/langspec/object.html
    
    under Attributes
    ----------------
    Replace the height attribute's description with:
    
     Indicates the vertical dimension for the resulting object 
     display. If necessary, the object is scaled to the specified
     size. The value of this attribute is a real number optionally
     following by a unit of measure from the set of pc, pt, px, in,
     cm, mm, em (picas, points, pixels, inches, centimeters,
     millimeters, and ems respectively).  The default unit is px
     (pixels). Possible values include: "5", "5in", and "10.5cm".
     If a height value is specified and no width value is specified,
     the width will be scaled by the same factor as the height.
     If both a height value and width value are specified, some
     implementations may not be able to scale the two directions
     by a different factor and may therefore ignore one of the
     two values.
