-		Images. Includes a scaling factor for LaTeX.
-		
-		To do: alternatively, allow defining the scaling factor by specifying what proportion of the page width the image should occupy (a la LaTeX [width] parameter).
-		How about a <latex-attributes> element that can be used to specify \includegraphics arguments?
-			<width keepaspectratio="yes">0.5\columnwidth</width>
-			<height>2cm</height>
-			<scale>0.5</scale>
-			etc.
-		
-		To do: if no description is given, use the basename as the content of the ALT element.
-		Ideally, I think we should be able to define two image formats (PDF, EPS, PNG, ...) when marking up an image: one for LaTeX output, another for HTML.  Mind you, if the generation of the various formats from a single master is handled outside of the XSLT processing...?
