Suppose that you have a stylesheet which customizes another stylesheet, perhaps changing the formatting of a few elements. Suppose that one of these elements is formatted by a complex template in the base stylesheet, and all you want to change is one small, special case. How can you do this?
The answer is with <xsl:apply-imports>:
... <xsl:import href="basestyle.xsl"/> ... <xsl:template match="table"> <xsl:choose> <xsl:when test="@role='something-special'"> <xsl:call-template name="special-table-handler"/> </xsl:when> <xsl:otherwise> <xsl:apply-imports/> </xsl:otherwise> </xsl:choose> </xsl:template>
