 *
 * NOTE: Due to the fact that the structure xsltElemPreComp is most

 * easily change it, we'll create an intermediate structure which will
 * hold an xsltElemPreCompPtr.
 * BIG NOTE: The only problem I see here is that the user processes the
 *  content of the stylesheet tree, possibly he'll lookup the node->psvi
 *  fields in order to find subsequent extension functions.
 *  In this case, the user's code will break, since the node->psvi
 *  field will hold now the xsltStyleItemExtElementPtr and not
 *  the xsltElemPreCompPtr.
 *  However the place where the structure is anchored in the node-tree,
 *  namely node->psvi, has beed already once been moved from node->_private
