xsl:include, paramterizable?

I would like to dynamically specify attribute sets (defined
in different xsl files) to include.

So I thought I'd do something like:

<xsl:variable name"styles">defaultstyles.xsl</xsl:variable>

<xsl:include href="<xsl:value-of select={$styles}>"/>

But, that didn't work (not terribly surprising).

Nor did:
<xsl:include href=<xsl:value-of select="{$style}"/>/>


It's looking like this sort of thing isn't possible.

Ideas?  Alternatives?  Bad syntax?

Thanks,

Joel
