Calling a template dynamically?

Hello everybody,
I'm trying to call a template whose name is in the XML file that I'm parsing.
Example:
XML file contains a tag like:
...
<label>sample</label>
...

And I want to call the template "sample".

Therefore I think that I would need to do something like:
<xsl:variable name="templatename">
<xsl:value-of select="label"/>
</xsl:variable>
<xsl:call-template name="$templatename">

but this doesn't work, as it doesn't the following:

<xsl:call-template name="{$templatename}">

Thank you very much for any help and best regards,

Costantino Sertorio
