# Return the node which represents the file into which everything gets rendered. This is normally
# the same node as <tt>#content_node</tt> but can differ in special cases. For example, when
# rendering the content of node called <tt>my.page</tt> into the output of the node
# <tt>this.page</tt>, <tt>this.page</tt> would be the +dest_node+ and <tt>my.page</tt> would be
# the +content_node+.
#
# The +dest_node+ is not included in the chain but can be set via the option <tt>:dest_node</tt>!
#
# The returned node should be used as source node for calculating relative paths to other nodes.
def dest_node
@options[:dest_node] || self.content_node
end
# Return the reference node, ie. the node which provided the original content for this context
# object.
#
# The returned node should be used, for example, for resolving relative paths.
def ref_node
@options[:chain] && @options[:chain].first
end
# Return the node that is ultimately rendered.
#
# This node should be used, for example, for retrieving meta information.
