				We have to be a little clever here, because we're

					(c) if the first thing following the <definition>
						is a <paragraph> or text node, it gets
						positioned correctly relative to the <keyword>.
 
				We know that the <keyword> won't have embedded

					hanging indent and finish. Note the use of
					child::node[1|2], because we don't necessarily know
					what variants of <keyword> and <definition> have

		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...?

		Include another XML/HTML/LaTeX document into the current one. If
		you don't specify @type, it assumes the type of document that
		you're currently generating (HTML or LaTeX).
		
		LaTeX documents are simply included using \input{...}. The old
		<latex-input> element is now deprecated.

		HTML documents are a little trickier, as there's no equivalent
		of \input{} in HTML, plus the XSLT processor always seems to
		generate a DOCTYPE when producing HTML, whether you want it or
		not, which means that you can only really include entire HTML
		documents, rather than HTML fragments (maybe you can turn this
		off?). The workaround currently is to embed the HTML document
		inside an <object>.

		A similar argument applies for plain text documents (such as
		code listings) that we want to include, but are externally
		generated and so can't just be embedded in the source XML.

		@type: The type of the document to be included. [optional] Valid
		values are:
			"xml"
			"html" [default for HTML]
			"latex" [default for LaTeX]
			"plain" (as in text/plain)
		
		@basename: Name of file to include (including suffix!).
		[required]
		
		@location: Path to file to include. Note that this gets a /
		appended to it. However, this shouldn't make any difference in
		normal usage. [optional]

		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...?

		Include another XML/HTML/LaTeX document into the current one. If

		you're currently generating (HTML or LaTeX).
		
		LaTeX documents are simply included using \input{...}. The old
		<latex-input> element is now deprecated.

		HTML documents are a little trickier, as there's no equivalent
		of \input{} in HTML, plus the XSLT processor always seems to
		generate a DOCTYPE when producing HTML, whether you want it or
		not, which means that you can only really include entire HTML
		documents, rather than HTML fragments (maybe you can turn this
		off?). The workaround currently is to embed the HTML document
		inside an <object>.

		A similar argument applies for plain text documents (such as
		code listings) that we want to include, but are externally
		generated and so can't just be embedded in the source XML.

		@type: The type of the document to be included. [optional] Valid
