With the DocBook configuration shipped with the XMLmind XML Editor
(XXE), images (referenced from within imagedata elements) that are wider
than the width of the document view are clipped on the right and the
left.  It seems that the red selection rectangle indicates the boundary
of the viewport (as described in "DocBook: The Definitive Guide" and in
the "Support of images in DocBook" document shipped with XXE).  Without
any view-adjusting attributes, it further seems that the width of the
viewport (that is, the width of the selector when an imagedata element
is selected) is equal to the width of the document view.  As such, I
thought that I could simply set the scalefit attribute to "1" to cause
the image to be scaled (down) to fit within this "default" viewport.
However, setting this attribute (by itself, in a case such as this) does
nothing - the image is still clipped.  What am I missing here?

Also, while I'm asking, what are the defaults for the various
view-generating properties that XXE imposes?  "DocBook: The Definitive
Guide" says, at several points, that "an implementation is free to
choose defaults"; I'm simply curious what defaults XXE chooses for the
various properties (depth, width, one when only the other is defined,
etc.).

Take care,
