Granted, the "presentation" part is confusing, not surprising considering
images are pretty much, well, presentational. However, they are referring
there to "border", "align", "vspace", "hspace" and others you *will* find in
the "Transitional" DTDs of HTML 4.01 and XHTML 1.0.

It doesn't apply to width and height. The HTMLish version of the DTD shown
at:
http://www.w3.org/TR/xhtml11/xhtml11_dtd.html
Indicates a reference to the Image Module at
http://www.w3.org/TR/xhtml-modularization/DTD/xhtml-image-1.mod
which reveals:
<!ATTLIST %img.qname;
%Common.attrib;
src %URI.datatype; #REQUIRED
alt %Text.datatype; #REQUIRED
longdesc %URI.datatype; #IMPLIED
height %Length.datatype; #IMPLIED
width %Length.datatype; #IMPLIED

Contrast that with XHTML 1.0 Transitional:
<!ATTLIST img
%attrs;
src %URI; #REQUIRED
alt %Text; #REQUIRED
name NMTOKEN #IMPLIED
longdesc %URI; #IMPLIED
height %Length; #IMPLIED
width %Length; #IMPLIED
usemap %URI; #IMPLIED
ismap (ismap) #IMPLIED
align %ImgAlign; #IMPLIED
border %Length; #IMPLIED
hspace %Pixels; #IMPLIED
vspace %Pixels; #IMPLIED
