public class StreamingApplyTemplates
extends ApplyTemplates

Streaming version of the xsl:apply-templates instruction. Available in Saxon-EE only. Only used for select="doc(..)" or select="document(...)" or select="doc(..)//x" etc. It is not used for other apply-templates instructions occurring in a streaming template.
