dinamic sorting question

Hi, dinamic sorting question
after visiting dpawsosn's XSLT Questions and Jeni Tennison web
I've found this solution to decide via variables how to sort:

<xsl:sort select="*[name()=$elemento]" data-type="{$tipo}" order="{$orden}"
/>

but it's not working, mabe the cause is transforming with Xerces2 Java
Parser 2.2.1?

thanks in advance
