Re: [xsl] saxon:preview doesn't work in 7.3 anymore

[michael.h.kay@xxxxxxxxxxxx]

the xsl (at the end of the e-mail) works under 7.2. But nothing happens under 7.3. 
Has anyone an idea whats on there? 
Or is it a bug in 7.3?

  <!-- A -->
 	<xsl:template match="A" mode="preview">	
             <xsl:variable name="AContent">
             <xsl:value-of select="@ID" />
           </xsl:variable>
            <xsl:variable name="adummy" select="saxon:setUserData('hrefid', $AContent)" />
	</xsl:template>

It's actually nothing to do with saxon:preview. At Saxon 7.3, variables that aren't referenced are no longer evaluated. This means that the trick of using <xsl:variable> to call an extension function with side-effects no longer works. You can force evaluation my marking the variable with saxon:assignable="yes", or by writing output that [appears to] depend on the variable - e.g. <xsl:value-of select="$adummy[0])"/>
