<xsl:value-of
> select="generate-id($context::following-sibling::*[position()=1])"/>

Others have pointed out the correct syntax here.

> </xsl:attribute>NEXT</xsl:element>
>         </xsl:when>
> 	    <xsl:otherwise>

>                 </xsl:variable>
>                 <xsl:call-template name="parentnext">
>                 <xsl:with-param name="context" select="$newcontent"/>

>         </xsl:choose>

NO! The parameter passed to parentnext will be a string containing an XPath
expression, it will not be the result of evaluating that expression. There
is no way in standard XSLT of constructing an XPath expression at run-time
and then evaluating it. (There is a Saxon extension to do this, but I'm
fairly sure you don't need it here.)
