<!--
	Miscellaneous typographic symbols, including punctuation marks and logos (e.g., for LaTeX).
	
	Technically we don't need to disable output escaping for all of these, but it's probably better to code them all consistently, rather than trying to figure out which ones do need it (e.g., &#160; for a non-breaking space) and which ones don't (e.g., &amp;).

	The "strip" mode forms of the templates are for use in the context of an HTML <title> element (so the mode is only relevant to the HTML formats). Embedding HTML markup inside the <title> element causes the markup to appear verbatim in the window title, i.e., <title><em>foo</em> bar</title> will appear in the window title as "<em>foo</em> bar", not "foo bar". Putting the stylesheet into strip mode means that it will only output text nodes unless otherwise specified for a particular element. Generally the "strip" templates will simply call-template to the original, unless the original contains markup that needs to be eliminated (e.g., see space below).
	
	The downside of this approach, of course, is that you need "strip" mode templates for quite a lot of things, but that can't really be helped.
