the select-attribute is not an AVT and in general, an XPath cannot be 
interpreted, it is static. The "normal" way to go about this is to 
create a stylesheet that creates a (temporary) second stylesheet with 
the xpaths from your source and then apply that new stylesheet. Another 
way is to use extension functions (Saxon for one has extensions that 
work both in XSLT 1.0 and 2.0 that can do this).
