PrecedingOrAncestorEnumeration

public PrecedingOrAncestorEnumeration(NodeImpl node,
                                      NodeTest nodeTest)

This axis cannot be requested directly in an XPath expression but is used when evaluating xsl:number. It is provided because taking the union of the two axes would be very inefficient
