com.icl.saxon.expr.NodeSetExpression
com.icl.saxon.expr.NodeListExpression
A NodeListExpression is an expression denoting a set of nodes sorted in document order. 
 It is not possible to write a NodeListExpression directly using XPath; however a node set
 expression is treated as a NodeListExpression when it appears in certain contexts, specifically
 the select attribute of xsl:apply-templates or xsl:for-each.
