+There are two other packages contained in C<lib/MT/Template.pm> which define
+methods for searching/manipulating the tokens (I<MT::Template::Tokens>)
+created by C<MT::Builder::compile()> as well as their representative nodes
+(I<MT::Template::Node>). A token is an array reference made up of the
+following nodes listed alongside each node's position in the array.

+=item [0] Node name 
+
+If the token represents an MT template tag this node contains the tag name. If
+the node represents a text node, then it contains the word 'TEXT'.
+
+=item [1] Tag attributes or TEXT contents
+
+For tag tokens, this contains a hash reference of the attributes used with the
+tag and their values. For TEXT nodes, this contains the body of text it
+represents.
+
+=item [2] Compiled node contents
+
+This node holds the current token's child tokens as returned from
+C<MT::Builder::compile()>. Hence, if this node has a value, it indicates that
+the current token represents a container (or C<BLOCK>) tag. The uncompiled
+version is stored in the following node.

+
+This node contains the uncompiled (i.e. non-tokenized) version of contents of

+that's the case).
