Yes, I use modes extensively
http://www.gerixsoft.com/blog/xslt/pipeline
http://www.gerixsoft.com/blog/xslt/include-mode-new

but what I need, is to separate static portion of xpath to use-when, 
both for speed and readability purposes, conditions can be quite complex:
<xsl:template match="some-xpath1" 
use-when="$first-config-option=('A','B') or $another-config-option='C'">

where config options are set on TransformerFactory level

any ideas?
