org.apache.xml.dtm.DTMAxisTraverser.first()
By the nature of the stateless traversal, the context node can not be returned or the iteration will go into an infinate loop. So to traverse an axis, the first function must be used to get the first node.
This method needs to be overloaded only by those axis that process the self node. <\p> @param context The context node of this traversal. This is the pointthat the traversal starts from. @return the first node in the traversal.
