I've found other ways to solve the task:

1. Use XInclude

<xi:include href="configuration:is-xxx">
 <xi:fallback>
   <xsl:include href="included.xslt"/>
 </xi:fallback>
</xi:include>

This should resolve "configuration:is-xxx" to dummy xml,
if we do not want to include xslt, and fail to resolve it 
if we do want to include xslt.

For this to work one needs to supply an XMLEntityResolver to the XInclude
(xerces parser).

Unfortunately it's not easy in Saxon, and to intrinsic even for xerces.

2. Special xslt uri resolver

 <xsl:include href="configuration:is-xxx included.xslt"/>

This assumes uri which is resolved to dummy or to a specified xslt,
depending on value of "configuration:is-xxx".

Thanks.
