...alternatively, if there's no solution to:

> how can I call a named template, where the name of the template I
want to call is stored in a variable?

then how about a way to call the XSL inside the <behavior> element (below),
as if it were a named template?

	<rule selector="span.symbol">
		<behavior>
			<xsl:choose>
				<xsl:when
test="text()='|'">&#x25B6;</xsl:when>
			</xsl:choose>
		</behavior>
	</rule>
