/**
 * XPath configuration to use.
 * 
 * This is a counter-measure against
 * #96: When using
 * Saxon-HE, you have stripped down XPath support (no XPath higher order
 * functions according to the saxon
 * feature matrix). In this case, you perhaps want to use a different
 * XPath implementation (most commonly the XPath implementation shipped
 * with Java).
