Can't do this.You can do something like:

<xsl:choose>
 <xsl:when test="$condition='choice1'">
   <xsl:call-template name="choice1"/>
 </..
 <xsl:when test="$condition='choice2">
   <xsl:call-template name="choice2"/>
..etc..

In java you would create a Templates object and cache that. That will 
resolve your includes/imports once and so your only performance hit 
would be building that object. Then you would build the transformer off 
of the templates object.

I have many imports (around 15) and pretty complex XSL. After building 
the Templates object, my transforms are are in the 20-30 millisecond 
range. I haven't had to scale my app to several thousands of users so I 
don't know what how that would affect my transform speed.
